Hi ricardo, i tried this before,but set option attribute can only let first box selected on "B" it won't trigger second box get data from database. second box won't change until you click on the first box and select other options
all i want is first box selected on "B" and second box selected on "B2" automatically when page loaded. i still added selected="selected" on option "B". here is the sample page http://sskes.damimi.org/test/ thanks anyway.
