Page not displaying properly in IE 6

1

I have created a survey for a client of ours; the form works okay on firefox, but displays incorrectly in IE6. Text is flowing ff the page, and worst of all the radio buttons that should appear halfway through aren’t there at all. I removed the CSS sheet from the page, just in case it was a CSS thing, but that hasn’t fixed the error with the radio buttons. Can anyone help?
