Guictrlread Issue

[exodius]

I have this gui that thus far just checks to see if a file exists.. But even before getting that far, I just want to read the Input each time the "Fix" button is pressed so I can check again if the file doesn't exist. The problem I'm having is I can click "Fix" once and it works fine. If I press it again, the $filename = GUICtrlRead ($filename) line returns 0. Should I have that somewhere else?

#include <GUIConstants.au3>
GUICreate("Enter Filename to Fix", 451, 94, 296, 184)
GUICtrlCreateLabel("Enter the filename of the .csv file you converted.", 8, 8, 437, 24)
GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif")
GUICtrlSetColor(-1, 0xFF0000)
$filename = GUICtrlCreateInput("filename.csv", 24, 48, 313, 28, -1, $WS_EX_CLIENTEDGE)
GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif")
$Fix = GUICtrlCreateButton("Fix", 360, 48, 75, 25)
GUICtrlSetFont(-1, 12, 800, 0, "MS Sans Serif")
GUISetState(@SW_SHOW)
While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
        Case $msg = $Fix
            FixFile()
    EndSelect
WEnd

Func FixFile()
$filename = GUICtrlRead ($filename) 
    If $filename <> "" Then
        If FileExists ( $filename ) Then 
            MsgBox ( 0, "", "Bingo" )
        Else
            MsgBox ( 0, "File not found!", "The file was not found. Make sure that the file """ & $filename & """ is in the same folder as this program." )
        EndIf
    Else
        MsgBox ( 0, "Enter filename", "You must enter a filename to fix before clicking the ""Fix"" button." )
    EndIf
EndFunc

try this

#include <GUIConstants.au3>
global $filename
GUICreate("Enter Filename to Fix", 451, 94, 296, 184)
GUICtrlCreateLabel("Enter the filename of the .csv file you converted.", 8, 8, 437, 24)
GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif")
GUICtrlSetColor(-1, 0xFF0000)
$filename = GUICtrlCreateInput("filename.csv", 24, 48, 313, 28, -1, $WS_EX_CLIENTEDGE)
GUICtrlSetFont(-1, 12, 400, 0, "MS Sans Serif")
$Fix = GUICtrlCreateButton("Fix", 360, 48, 75, 25)
GUICtrlSetFont(-1, 12, 800, 0, "MS Sans Serif")
GUISetState(@SW_SHOW)
While 1
    $msg = GuiGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
        Case $msg = $Fix
            FixFile()
    EndSelect
WEnd

Func FixFile()

    If GUICtrlRead ($filename) <> "" Then
        If FileExists ( GUICtrlRead ($filename) ) Then
            MsgBox ( 0, "", "Bingo" )
        Else
            MsgBox ( 0, "File not found!", "The file was not found. Make sure that the file """ & GUICtrlRead ($filename) & """ is in the same folder as this program." )
        EndIf
    Else
        MsgBox ( 0, "Enter filename", "You must enter a filename to fix before clicking the ""Fix"" button." )

Awesome, I knew it would be some little fix like that, I just couldn't think of what it would be. Many thanks!
