I'm searching for days now, and it doesn't work. What I want to do is this.
I have a form with 2 list/menu's. Both are filled with databaserecords.
The trick i want to do is, when in the first list/menu I select a clientname, then automatically the second list/menu shows only his products.
both content is database driven, so maybe somebody can help me out?

thx for your help.
