I have mentioned in the initial email that if I just allow users to type stuff, it passes the form back to itself and works. However, what I want to do is to allow users click one radio button/checkbox, and use that value to determine which "select menu" to bring up. However, the information I am only interested in storing, is the value of the select menu and not the radio button/checkbox. Am I making sense here?
