I was trying to learn the compare function and I've decided to open the tutorial (step 2)

I want to use a value that I can toggle with a button at any given time.

I hope someone can tell me what's missing, here's the code:

Code:
[ENABLE]

aobscanmodule(test,Tutorial-i386.exe,89 83 80 04 00 00 8D 55 D4 E8 12) // should be unique
alloc(newmem,$1000)

label(code)
label(return)
label(hack)
label(value)

registersymbol(value)

value:
dd 0

newmem:
cmp [value],1
je hack

code:
  mov [ebx+00000480],eax
  jmp return

hack:
mov [ebx+00000480],#1000
jmp return

test:
  jmp newmem
  nop
return:
registersymbol(test)
[DISABLE]

test:
  db 89 83 80 04 00 00

unregistersymbol(value)
dealloc(newmem)


If that helps:

"value" is a label. It's used to define an address relative to a previous address. There is no previous address above "value" in that script.

Code:
alloc(newmem,2048)
label(value)

value:  // wrong: CE doesn't know where "value" is
  dd 0

newmem:
 // code...

Code:
alloc(newmem,2048)
label(value)

newmem:
 // code...

value:  // OK: "value" is an address somewhere after the code stored at "newmem"
  dd 0


Alternatively, declare "value" using alloc instead of label.
Code:
alloc(newmem,2048)
alloc(value,4)

value:  // OK: CE allocated memory specifically for "value"; it stands on its own
  dd 0

newmem:
 // code...
