Please could you help me with an issue I have. I am using two different javascript controls together one from the Yahoo UI library and another from http://www.openwebware.com/. They work great seperatly, but when I try to use them together IE7 just dies with a very unhelpfull message. After, many, mnay hours of trying to get it to work, I have a situation now that when I have form tags surrounding the elements they don't work. But, when you remove the form tag; the sun shines and birds sing.

So please could you have a look over this and see if you can spot something I have stupidly missed. Thanks.
