Error Subscript used on non-accessible variable putting data into an array

[Jibberish]

I am trying to add data to an array and I keep getting the error "Subscript used on non-accessible variable ".

expandcollapse popup

#include <array.au3>
; Includes, etc

Local $aOptionsArray[3]

$aOptionsArray = CheckboxesAndRadioButtons()
_ArrayDisplay($aOptionsArray)
Func CheckboxesAndRadioButtons()
; Create Checkboxes and Radio Buttons and read the results
~
~
~
    ; Radio Buttons to Array
    ; $aOptions[0] = $bTestSelectForever
    ; $aOptions[1] = $bTestSelect3Times
    ; $aOptions[2] = $bTestSelectOnce
    
    If $bSelect1 = 1 Then
        $aOptions[0] = "True"
    Else
        $aOptions[0] = "False"  <<< This is where the error occurs.
    EndIf

    If $bSelect2 = 1 Then
        $aOptions[1] = "True"
    Else
        $aOptions[1] = "False"
    EndIf

    If $bSelect3 = 1 Then
        $aOptions[2] = "True"
    Else
        $aOptions[2] = "False"
    EndIf
    Return $aOptions
EndFunc

Is putting data into an array while in a If - Then - Else illegal?

Your defined array is named $aOptionsArray, but you are using it later as $aOptions, which doesn't exist.

Apologies - it is defined in the Function.  Updated script below. From what I understand if I create an array in a function and then return the array I need two different variable names - one in Main and one in the function. Yes?

Local $aOptions

        $aOptions[2] = "True"

    Return $aOptions
EndFunc

OK I figured it out. I neglected to put a [3] after my declaration.

Local @aOptions[3] solved the issue.

This is weird because usually when I declare an array in other code I don't have to add [x] as in :

Local $aArray  << has worked before

vs

Local $aArray[3]  << required for this particular script... I don't understand why!

[Danp2]

Probably because you are using a function that returns an array as a result, ie:

$aArray = ProcessList()

Jibberish,

An alternative approach.  Nota Bene, for this to work the controls must be defined consecutively.  This is handy for a large number of controls that can change...

; *** Start added by AutoIt3Wrapper ***
#include <GUIConstantsEx.au3>
; *** End added by AutoIt3Wrapper ***

#include <array.au3>
; Includes, etc

#AutoIt3Wrapper_Add_Constants=n

Local $aOptionsArray[3]

; lots of other code

Local $gui010 = GUICreate('Test')
Local $bSelect1 = GUICtrlCreateCheckbox('#1', 10, 10, 100, 20)
Local $bSelect2 = GUICtrlCreateCheckbox('#2', 10, 30, 100, 20)
Local $bSelect3 = GUICtrlCreateCheckbox('#3', 10, 50, 100, 20)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $gui_event_close
            Exit
        Case $bSelect1 To $bSelect3
            _CheckboxesAndRadioButtons()
            _ArrayDisplay($aOptionsArray)
    EndSwitch
WEnd

Func _CheckboxesAndRadioButtons()

    ; Create Checkboxes and Radio Buttons and read the results
    ; all variables in this Function were assigned either at the top of the script or in the function.
    ; Radio Buttons to Array
    ; $aOptions[0] = $bTestSelectForever
    ; $aOptions[1] = $bTestSelect3Times
    ; $aOptions[2] = $bTestSelectOnce

    For $i = 0 To UBound($aOptionsArray) - 1
        $aOptionsArray[$i] = (GUICtrlRead(Eval('bSelect' & $i + 1)) = $gui_checked) ? 'True' : 'False'
    Next

EndFunc   ;==>_CheckboxesAndRadioButtons

Also, it might be helpful for you to read (re-read) the helpfile sections concerning "scope" and function calls (byref vs. value).
