Hi,
Can anyone tell me why when following the Multilevel Pointers tutorial i get this error:

Scan error: thread 0: ‭17BBBA0‬ is an invalid value (100)

When i find the address (017BBBB8) then select what access the value, i get an offset of 18.
When i then do a scan with HEX box ticked on 17BBBA0 i get the above error.
I have even tried array of byte instead of whats shown in tutorials with 4 Bytes selected.
With array of bytes i get nothing as if the address doesnt exist.
Thanks

remove the space(s) behind the address (I'll fix it)
