I have a form that shows/hide different info depending on which radio button you click. The code works fine in everything except IE7 (haven’t tested IE6 but we are not supporting that anymore 🙂 )
The script is triggered by the first set of radio buttons (Account type)
The fiddle is here:

I’m pretty sure your markup is invalid, I wouldn’t use a
fieldsetas direct descendant to anulelement. Try validating your markup using the W3C validator.
