what's wrong ?

aobscan(INJECT,xx xx xx xx xx xx xx xx xx xx xx) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
fld dword ptr [eax+18],(float)90
fstp dword ptr [ebp-30]
jmp return

INJECT:
jmp code
nop
return:
registersymbol(INJECT)

[DISABLE]
//code from here till the end of the code will be used to disable the cheat
INJECT:
db xx xx xx xx xx xx xx xx xx xx xx

unregistersymbol(INJECT)
dealloc(newmem)
