I made an error in the first post, so your post makes sense There are 5 items in the Radiogroup, which I'm trying to select the last one with 4, but the error still exits. I have tried other methods like .SetItemIndex(4) also doesn't work, but I forgot the error type.

It's a little unclear exactly what you require. Is it the last item in the radiogroup whose caption contains the number 4? If so clarify so that I can modify the code.

This code will demonstrate how to select the last item but one in a radiogroup.

Code:

if f then f.destroy(); f = nil end
f = createForm(getMainForm())
f.Name = 'frmMain'
f.Caption = 'Main Form'
f.Width = 300
f.Height = 275
f.centerScreen()
--------------------------------
local rg = createRadioGroup(f)
rg.Align = 'alTop'
rg.Name = 'rg'
rg.Height = f.Height - 30
rg.Caption = 'Select Item'
rg.Columns = 2
rg.OnClick = function(sender)
-- Set the form's caption to the selected index of the radio group.
-- We add 1 to the ItemIndex because radiogroup's item objects are 0-based.
f.Caption = 'Selected Index: ' .. tostring(sender.ItemIndex+1)
end

local function init()
-- Create a temporary StringList to store the values for the radiogroup.
local sl = createStringList(f)
-- Let's loop through and create 10-items and add them to the StringList.
for i = 1, 10 do
sl.add('Item ' .. tostring(i))
end
-- Assign the radiogroup's items to those of the StringList.
rg.Items = sl
-- Finally, free the StringList because it's no longer needed.
sl.destroy()
end

local btn = createButton(f)
btn.Align = 'alBottom'
btn.Name = 'btnSelect'
btn.Height = 30
btn.Caption = 'Click'
btn.OnClick = function()
-- StringList item components are 0-based, meaning the first item is at index 0.
-- So we subtract 1 from the total count to get the correct count.
local count = rg.Items.Count - 1
-- Finally, set the ItemIndex of the radiogroup to the total count minus one.
rg.ItemIndex = count - 1
end

-- Lastly, execute the init function.
init()

I have commented lines for clarification.

I opened a blank CE and inserted

Code:

function selectradiogroup()
if f then f.destroy(); f = nil end
f = createForm(getMainForm())
f.Name = 'frmMain'
f.Caption = 'Main Form'
f.Width = 300
f.Height = 275
f.centerScreen()
--------------------------------
local rg = createRadioGroup(f)
rg.Align = 'alTop'
rg.Name = 'rg'
rg.Height = f.Height - 30
rg.Caption = 'Select Item'
rg.Columns = 2
rg.OnClick = function(sender)
-- Set the form's caption to the selected index of the radio group.
-- We add 1 to the ItemIndex because radiogroup's item objects are 0-based.
f.Caption = 'Selected Index: ' .. tostring(sender.ItemIndex+1)
end

local function init()
-- Create a temporary StringList to store the values for the radiogroup.
local sl = createStringList(f)
-- Let's loop through and create 10-items and add them to the StringList.
for i = 1, 10 do
sl.add('Item ' .. tostring(i))
end
-- Assign the radiogroup's items to those of the StringList.
rg.Items = sl
-- Finally, free the StringList because it's no longer needed.
sl.destroy()
end

local btn = createButton(f)
btn.Align = 'alBottom'
btn.Name = 'btnSelect'
btn.Height = 30
btn.Caption = 'Click'
btn.OnClick = function()
-- StringList item components are 0-based, meaning the first item is at index 0.
-- So we subtract 1 from the total count to get the correct count.
local count = rg.Items.Count - 1
-- Finally, set the ItemIndex of the radiogroup to the total count minus one.
rg.ItemIndex = count - 1
end

-- Lastly, execute the init function.
init()
end

Does not create a a form or radiogroup, so executing init() seems like it won't work.
My request is simple what is the syntax for the radiogroup I have, to select the last radio. I posted the command that I use and it generates an error.

I addd the fuction because the first time I tried it, error. However after deleting the funtion, I get a main form with 10 items, number nine is selected.
Now without a lot of code, what is the correct snytac to my initial question. The abovfe3 may answer for you but it doesn't answer to me, sorry.
trainer.characters_rg.ItemIndex = 4; = error. What does it need to be to select item 4 in the group?

Trainer Name or Gui Table name: trainer

RadioGroup Gui name: trainer.characters_rg

RadioGroup items: 0,1,2,3,4 -- last: 4

Code:

rg = trainer.characters_rg
local count = rg.Items.Count -1 -- rg.Items.Count: 5, rg.Items.Count -1: 4
print(count) --> 4
rg.ItemIndex = count -- select RadioGroup items: 4 (or tonumber(count))

characters table name: characters or trainer1.characters

characters table items: 1,2,3,4,5

Code:

rg = trainer.characters_rg
local count = rg.Items.Count -1 -- rg.Items.Count: 5, rg.Items.Count -1: 4
print(count) --> 4
rg.ItemIndex = count -- select RadioGroup items: 4 (last)
local tableCount = tonumber(rg.ItemIndex) + 1
trainer1.characters[tableCount] -- select table items: 5 (last)

I had asked for clarification of your request. It just seems like you want to select index 4. So whatever your radiogroup component is named use this:

Code:

my_radiogroup_component.ItemIndex = 3

As explained, indices used by the radiogroup are 0-based meaning that the first item is at index 0, the second item at index 1, the third item at index 2 and so on. If you take the time to read the comments and the code, perhaps you can understand it and learn from it.

Precisely what I wished. Thanks for the clear, concise answer that I already was using. With that I debugged other parts of the code and found the error, and trainer.characters_rg.ItemIndex = 4; was not the error.

like this...

Code:

if f then f.destroy(); f = nil end
f = createForm(getMainForm())
f.Name = 'frmMain'
f.Caption = 'Main Form'
f.Width = 300
f.Height = 275
f.centerScreen()
--------------------------------

radioGroup = createRadioGroup(f)
radioGroup.Caption = 'Options'
radioGroup.Items.add('Option 1')
radioGroup.Items.add('Option 2')
radioGroup.Items.add('Option 3')
radioGroup.ItemIndex = -1

-- Function to execute when the value changes
function radioGroupSelectionChanged(Sender)
ShowMessage('RadioGroup.Index: '..tostring(radioGroup.ItemIndex))
if radioGroup.ItemIndex == 0 then ShowMessage('First item selected') end
if radioGroup.ItemIndex == 1 then ShowMessage('Second item selected') end
if radioGroup.ItemIndex == 2 then ShowMessage('Third item selected') end
end

-- Set the function to be executed on change
radioGroup.onSelectionChanged = radioGroupSelectionChanged

Then just set cheat for each rg item index on line '...if.....then....end'
