Please see my response to Mr. Winter. What's in the javascript file?
Here is an HTML file which shows two ways of hiding text.

<body>
<p>Please try out our form.</P>
<P>This form uses the CSS display
and visibility style attributes. When you click on the
radio button email, Javascript code uses the display attribute
property of hidden to exclude the address field from the display.
No space will be taken up in the window.
When you click on the no radio button, Javascript code uses the
visibility attribute property of none to make the literature
catagories invisible. Space will be taken up in the window.</p>
