G'day Donal, you could try : $oLayer -> set('classitem','SessionID'); $oClass  = ms_newClassObj($oLayer); $oClass -> setExpression($sessionvalue); The _expression_ might need to be quoted, I don't know if setExpression does this? get it to output ($map->save()) a mapfile and check. good luck. cheers Ben --  Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome   WA   6725 [EMAIL PROTECTED] Out here, it pays to know...
