Use CFFORM (instead of <form>, and change your credit card input field to
something like this:
<cfinput type="text" name="CC" validate="creditcard" message="A valid credit
card is required.">
This does a bit better than the standard mod 10 test. The mod 10 test is
easy to circumvent - the number 91, for instance is seen as a perfectly
valid CC number. It's also client side, so the user cannot submit the form
with out it. You can also add the parameter ' required="yes" ' in the tag
to make it required.
