Quick ? about hidding and un-hidding things

[j0moran]

I made a form, and I want to make it so that if a User selects radio button "a" , then an input box will appear so that they can type INFO in. I have the input box already made and type = "hidden" now.. how would i make it re-appear when user selects radio button "a".
thx

Is there a way i can make fieldset disappear and re-appear?
I can make it disappear and what not...
and i try doing <fieldset name="sunset">
I type this to make it re-appear adn i get an error:
document.form.sunset.style.visibility = "visible";

The error i get is as follows:
document.form.sunset.style is null or not an object

Basically the purpose is because I have text b4 the input field, and I want that to be hidden also until the user selectes a certain option, Thats why im using a fieldset, and i put the text in the <legend> that was the only way i figured i could get the text b4 the input field to disappear and re-appear.
