Help with Functions or GUI... not sure

[Orangey]

Basically, I want to call a function inside my script. All I seem to get from the helpfile is that you use a number to call your function? What if I want to call a function by name? Also, is there such thing as calling a function without returning a value?

My real problem is, I have a script with a GUI inside of it- towards the end of the script. When the script and it gets to the GUI part, the GUI closes almost as soon as it is opened. Now, when I run that part of the script alone, it works fine.. buttons close it, etc... So I was thinking that it would be better to call the GUI as a function instead of just letting it stand there at the end of the script? Any advice?

Below is the GUI part:

#include <GUIConstants.au3>
#include <File.au3>
#include <GuiListView.au3>

$mydl = FileOpen ( "C:\ACTIVESCPS\TEMP\_SongList.txt", 0 )

$label_3 = GuiCtrlCreateLabel("Test Label", 240, 100, 170, 30 )
$button_2 = GuiCtrlCreateButton("Exit", 340, 220, 80, 30)
$button_3 = GuiCtrlCreateButton("Go!", 240, 220, 80, 30)

                FileWriteLine ( $itmselect, $ret_alb )
                _GUICtrlListViewDeleteItem($listview, $s_indices)

            EndIf

            Else
                MsgBox(0, "", "Please make a selection to continue.")
            EndIf

    EndSelect

FileClose($itmselect)

EDIT: Well, I went ahead and just made the GUI part into an exe which seemed to work okay.
