Code:

$servsize=getfilesize($servfile)
IF $wrksize<>$serversize

I would like to recommend you a header in your scripts like
Code:

If NOT @LOGONMODE
	Break On
EndIf
Dim $RC
$RC = SetOption("Explicit","On")	; <-- This will help you
$RC = SetOption("NoVarsInStrings","On")
$RC = SetOption("NoMacrosInStrings","On")
$RC = SetOption("WrapAtEOL","On")
