To do what you are suggesting could probably be done in a simpler way by using the implode function... but what I am really trying to do should give a result like the one in my original post. Problem is: the insert is not always going to be the same length; that is there may be 2 categories selected or 3 or 4 so the insert statement has to be created on the fly. So, far no one has figured out a way to do it. :-( An alternative, and I'm going to try that now is to do a switch or case or whatever it is and set up 3 or 4 inserts with 1 to 4 VALUES and then populate them from the array. Or another way may be even simpler: implode the array and save to one field and when querying explode it. :-) -- unheralded genius: "A clean desk is the sign of a dull mind.
