Subject: Re: Multiple Selects in a JSP From: "Ken Holzer" <[EMAIL PROTECTED]> === Thanks Larry,
I was able to get this to work. I do have a related question. I have a jsp page that shows a history of activities I have the same two select fields on this jsp. Each row on the page is its own form so that they can be updated seperately. Is there a way to fill the second select list based on the value of the first list when the page is populated. I have gotten it to change when the 1st select is changed, but ai want it to display correctly when the page is first displayed.
