Weirdest bug i've ever seen

[=sinister=]

I have a simple GUI, and in that GUI I have a button. when the button is pressed it calls the convertCoordinates udf:

expandcollapse popup

Global $retour, $xul, $xlr, $yul, $ylr

Func convertCoordinates($wowzoneID, $wowXcoord, $wowYcoord)
    For $i = 1 To _FileCountLines("./Database.txt")
        $Split = StringSplit(FileReadLine("./Database.txt", $i), ",")
        Global $uselessID = $Split[1]
        Global $continentID = $Split[2]
        Global $zoneID = $Split[3]
        Global $zoneName = $Split[4]
        Global $xul = $Split[5]
        Global $xlr = $Split[6]
        Global $yul = $Split[7]
        Global $ylr = $Split[8]
        If $wowzoneID = $Split[3] Then
            $pctWidthValue = getWidth() / 100
            $pctHeigthValue = GetHeight() / 100
            
            $xValue = $xul - ($pctWidthValue * $wowXcoord)
            $yValue = $yul - ($pctHeigthValue * $wowYcoord)
            ExitLoop
        EndIf
    Next
    Return Round($xValue, 1) & ", " & Round($yValue, 1)
EndFunc
    
Func getWidth()
    $retour = 0
    $retour = $xul - $xlr
    If $xul < 0 And $xlr < 0 Then $retour = (0 - $xlr) - (0 - $xul)
    Return $retour
EndFunc
    
Func getHeight()
    $retour = 0
    $retour = $yul - $ylr
    If $yul < 0 And $ylr < 0 Then $retour = (0 - $ylr) - (0 - $yul)
    Return $retour
EndFunc

however, when the udf is called, it changes the value of the button in the GUI to some weird numbers. I don't even have a GUICtrlSetData() in there?! I'm sooooooooo confused.

There's no GUI and no button in that code... makes it hard to reproduce your symptoms...
