Call function on combo box selection?

[pete1234]

I have a very simple GUI which consists of a single combo box with 2 possible values. I would like to call a function when one and only one of these values is selected, but I can't get things to work correctly. I'm trying to work in steps to get to that point, but I'm getting stuck pretty early on. Here's what I have right now (I've stripped out code that is irrelevant to this problem):

Global $buCountDefault = "Specific";0
                Global $buCountGlobal = "Global";1
                GUICtrlCreateLabel("How many backups should be kept?", 10, 65, 200, 20)
                    If FileExists($buIniPath) Then
                        Local $buCountReadDefault = IniRead($buIniPath, "BackUp.Settings", "count", $sIniErrorMsg)
                    Else
                        $buCountSetDefault = $buCountDefault
                    EndIf
                    If FileExists($buIniPath) And $buCountReadDefault = 0 Then
                        $buCountSetDefault = $buCountDefault
                    EndIf                       
                    If FileExists($buIniPath) And $buCountReadDefault = 1 Then
                        $buCountSetDefault = $buCountGlobal
                    EndIf   
                $sConfigComboCount = GUICtrlCreateCombo($buCountDefault, 10, 85)
                GUICtrlSetData(-1,$buCountGlobal,$buCountSetDefault)
                $buCountRead = GUICtrlRead($sConfigComboCount)
                                
                GUISetState ()

                While 1
                    $sMsg = GUIGetMsg()
                    Select
                        Case $sMsg = $GUI_EVENT_CLOSE Or $sMsg = $sCancel
                            GUISetState(@SW_HIDE)
                            ExitLoop
                        Case $sMsg = $sConfigComboCount; I haven't added criteria here yet because I can't get the basics working
                            Msgbox(0, "", $buCountRead)
                        EndSelect
                Wend

I'm using the MsgBox just for testing right now, and it always returns the default value of the combo box instead of the selection. Anyone know where I'm going wrong? Thanks a bunch.

Think about it, you read the value right after the combo is created, not when it is changed, you understand what I mean??

(move the GUICtrlRead() to after the Case)
