Variable used without being declared

Hello,

I want to check if a global variable is set or not and set from within the function.

Can someone help me why am I getting "Variable used without being declared." for "$CHECK"?

#include <GUIConstantsEx.au3>

AutoItSetOption('MustDeclareVars', 0)

GUICreate("DUMMY", 532, 450, -1, -1)
GUISetState(@SW_SHOW)

chk()

While 1
    $nMsg = GUIGetMsg()
        Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        EndSwitch
WEnd
    
Func chk()
    If IsDeclared($CHECK) Then
    EndIf   
EndFunc

The code you have is sorta redundant with your Opt command. Delectation of vars is forced by you, this it is checked before the script is executed. IsDeclared is run time, it won't get that far due to the compiler compiler (AU3Check).

Post your code because code says more then your words can. SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y.
