ImageSearch error...? why?

[giorgio007 0]

Hy all!
What's the problem?

Func _ImageSearch($findImage, $resultPosition, ByRef $x, ByRef $y, $tolerance, $transparency = 0)
        Return _ImageSearchArea($findImage, $resultPosition, 0, 0, @DesktopWidth, @DesktopHeight, $x, $y, $tolerance, $transparency)
EndFunc   ;==>_ImageSearch

Func _ImageSearchArea($findImage, $resultPosition, $x1, $y1, $right, $bottom, ByRef $x, ByRef $y, $tolerance, $transparency = 0)
        ;MsgBox(0,"asd","" & $x1 & " " & $y1 & " " & $right & " " & $bottom)
        If Not ($transparency = 0) Then $findImage = "*" & $transparency & " " & $findImage
        If $tolerance > 0 Then $findImage = "*" & $tolerance & " " & $findImage
        $result = DllCall("ImageSearchDLL.dll", "str", "ImageSearch", "int", $x1, "int", $y1, "int", $right, "int", $bottom, "str", $findImage)

        ; If error exit
        If $result[0] = "0" Then Return 0

        ; Otherwise get the x,y location of the match and the size of the image to
        ; compute the centre of search
        $array = StringSplit($result[0], "|")

        $x = Int(Number($array[2]))
        $y = Int(Number($array[3]))
        If $resultPosition = 1 Then
                $x = $x + Int(Number($array[4]) / 2)
                $y = $y + Int(Number($array[5]) / 2)
        EndIf
        Return 1
EndFunc   ;==>_ImageSearchArea

what does it mean? 

anyone could help?

Add a space after the comma and before the keyword, probably the ByRef, it's not an AutoIt3 error, it's an AU3Check issue that I believe has been fixed in updated versions of it.
