I don't think there is a better way, I'm just suggesting maybe hardcoding those to drop downs for testing purposes, and eliminate the JS. You're JSP looks right, and I'm assuming that your form bean has the return values as arrays if their multi-select, or single strings and they're otherwise set up exactly the same. Technically you're submitting the same form twice, so it should be working. I'm wondering if it will work without the javascript based on the theory of boiling down the problem to it's aboslute basics, and that would be: are you in fact set up correctly to submit 2 select tags at once. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
