display text field based on the selection choices

[John Davis]

I want to display credit card fields when the user selects the option paid
membership. If user selects the option free membership, then the credit card
text field will disappear. Here's the code I did with JavaScript but didn't
work.

What about users without javascript?

You could always do something put the option on page one, then test for the
value of the option on the next page, and generate the credit card based on
that.
