checking a Variable error

[youtuber]

If $aList[$n] is finished, it gives an error.
How do I need to provide control for this?

To be logical, should the StringSplit be outside the loop ?  And when you reach the end, should the Button1 be disabled ?

@argumentum Actually instance is seamless nice, thanks.

Actually, should GUICtrlSetData ($Button1, "Done") and disable the button
like this

Case $Button1
            $aList = StringSplit(GUICtrlRead($Edit1), @CRLF, $STR_ENTIRESPLIT)
            If GUICtrlRead($Button1) = "Next" Then
                $n += 1
                If $n > $aList[0] Then
                    GUICtrlSetData($Button1, "Done")
                    GUICtrlSetState($Button1, $GUI_DISABLE)
                    ContinueLoop
                EndIf

                $ReadString = StringRegExp($aList[$n], '[a-zA-Z0-9_\\.-]+@[a-zA-Z0-9\-]+\.+[a-zA-Z0-9]{2,4}', 3)
                If IsArray($ReadString) Then GUICtrlSetData($Input1, $ReadString[0])
                GUICtrlSetData($Button1, "Pass")
            Else
                GUICtrlSetData($Button1, "Next")
            EndIf

@Nine Thanks for trying to find out another example would be nice.
