Responding to button clicks with multiple GUIs

[Travis]

I have a program that will open another window when a button is pressed. I manged to get it to close only that window if the X button is pressed, but whenever I create my own buttons on that Window it says the variable is not defined. Here is my example

Case $msg[0] = $egg
        Global $lol
        MsgBox(0,"oh noes","you fund the egg!")
        $lol = GUICreate("Très bien!",310,400)
        GUISetState(@SW_SHOW,$lol)
        GUICtrlCreatePic(@ScriptDir & "\cake.GIF",1,1,307,370)
        $cegg = GUICtrlCreateButton("Ok, fun's over!",105,375,100,25)
    Case $msg[0] = $cegg
        GUIDelete($lol)
    EndSelect
WEnd

However, I get this error when trying to compile

C:\Documents and Settings\Travis\My Documents\Google Suggest API.au3 (60) : ==> Variable used without being declared.:
Case $msg[0] = $cegg
Case $msg[0] = ^ ERROR

Now my question is, how can I get the GUI to respond to those clicks? It seems the variable for the button is isolated to just that one Case, eventhough I manged to get the $GUI_EVENT_CLOSE to work for _both_ of my window, with this

Case $msg[0] = $GUI_EVENT_CLOSE
        If $msg[1] = $main Then
        FileDelete(@ScriptDir & "\output.file")
        Exit
    Else
        GUIDelete($lol)
        EndIf

Can anybody clear this up, I looked on the online documentation too. Thanks in advance.

1

Place at the top of the Script

Global $cegg

this might not work correctly, but you can give it a try

2

Create the GUI before the Case statements and use the buttons to "hide" and "Show" the GUI rather than create and delete it

3

you can place a secondary while/wend loop when the GUI is created. then that loop will exit when the GUI is closed

Thank you very much. I tried the first and third already, but did not think of the second and that is what got it to work.
