Thanks Jochen your bit works like a dream, just the AS part now, does that look right as it is not finding the PC-01 in the array?

code:
	Dim $List	

	For $Loop = 0 to $sExcludedList.ListCount-1
		
		$sExcludedList.ListIndex = $Loop
		$List = $List + $sExcludedList.Text
     	If $Loop < $sExcludedList.ListCount - 1 
      		$List = $List + "," 
		EndIf
	Next
	
	$xArray = Split($List,",")
	
	If AScan($xArray,$sExcludedInput.Text) = 1
		? $sExcludedInput.Text + ' is Present.'
	Else
		? $sExcludedInput.Text + ' is NOT Present.'
	EndIf
