I have a script that I use for installing MS updates on computers. I am implementing something to check actual file version, due to some of the updates not creating reg files when slipstreamed into the install. I wrote a function to perform what i need, and it works fine. When i move it into a different script (so it can be a more universal), it always says it cant find the file - even though I display the contents and they are fine. Here's a snippet of the script. Please let me know if you need more.
Here's how it flows. I call Script A. It then calls Script B for checking. Anytime an update is needed, Script E is called (and performs the update). It works in Script B, but not in Script E. I use all Calls and Returns.


Code:
  
Function UpdatedFileList()
	$ArraySize = 0
	$filename = "$ScriptDir\fileupdatelist.csv" ; This file is in the format: KB######,Filename,FileVersion
	If Open(1,$filename) = 0 
		$line = ReadLine(1) 
		While @error = 0  
			$x = Left($line,8)
			If $x = $KBNumber
				$ArraySize = $ArraySize + 1
			EndIf
		$line = ReadLine(1) 
		Loop 
		$=Close(1)
	EndIf
	If $ArraySize == 0
		Return
	EndIf
	
	
	Dim $array[$ArraySize-1,1]
	$ArrayCount = 0
	If Open(1,$filename) = 0 
		$line = ReadLine(1) 
		While @error = 0  
			$x = Left($line,8)
			If $x = $KBNumber

;				$=MessageBox("ArrayCount is $ArrayCount","$KBNumber",0)
				$LastComma = InStrRev($line,',')
				$array[$ArrayCount,0] = SubStr($line,10,$LastComma - 10)
				$array[$ArrayCount,1] = Right($line, Len($line) - $LastComma)
				$ArrayCount = $ArrayCount + 1
			EndIf
		$line = ReadLine(1) 
		Loop 
		$=Close(1)
	EndIf

	For $x = 0 to Ubound($array) ;$ArrayCount-1 ;
		$FileNameCheck = $array[$x,0] 
		$FileVerCheck  = $array[$x,1]
		$=MessageBox($FileNameCheck + '-' + GetFileVersion($FileNameCheck),"$KBNumber",0)
		
;		? "$array[$x,0]-$FileNameCheck;$array[$x,1]-$FileVerCheck"
		If GetFileVersion($FileNameCheck) < $FileVerCheck 
			$NeedUpdate = 'Y'
			? "$FileNameCheck;$FileVerCheck"
		EndIf
	Next
	$UpdatedFileList = $NeedUpdate
EndFunction
