Hi, I have a CustomValidator control which checks which option the user has selected. On submit, if the decline option is chosen, a check is made to make sure a comment is entered. I have the validation code on both the server and client side. However, nothing seems to happen when I run it up in Firefox. I read this article regarding the <xhtmlConformance mode="Legacy"/>. This didn't seem to be the problem as this option isn't set in my web.config file. Could someone help?
