Thanks! That works great, sort of.... I changed the return to only 'list' or 'string' or 'integer' for easy comparison. In a dtml doc or method it works fine. In a ZSQL it does not. Seems that it always sees the input parameters as strings...never a list - even when entered as a list. ['Ford','Dodge',''] is seen as a string when checked inside a dtml-if in the ZSQL method. Are Pythonscripts handled somehow differently inside a ZSQL method? Or something else??
