Thanks. I did just that but was left confused as to exactly how to use the array.
I took a different approach using 4 drop-downs populated by 4 recordsets, 3 of which have parameters based on the previous drop downs.
The select lists are set to submit on select. That works fine to get the drill downs but I cannot get the ultimate result which is an ID to post to another page.
Is there a way to set a Session Value on select? That would be a simple finish to what I have so far.
