Pro Forms Disappear when filling out the form

Having a strange issue. The PayPal Pro form fields are disappearing when in the process of filling out the forms on our site when using Chrome and Firefox. When using IE, we are unable to enter data in the fields at all. I’ve been searching the forum and I have yet to find a solution. I also tried using the Plugin Organizer pluigin mentioned in one of the posts to turn off all other plugins on this page. And even with only the S2member framework plugin active, the issue was still there. PLEASE HELP!

This is one of the pages that this is happening on:

This is my shortcode:
[s2Member-Pro-PayPal-Form level="1" ccaps="" desc="Level 1 Member / description and pricing details here." ps="paypal" lc="" cc="USD" dg="0" ns="1" custom="shockwaveonline.com" ta="0" tp="0" tt="D" ra="0.01" rp="1" rt="M" rr="1" rrt="" rra="2" accept="paypal,visa,mastercard,amex,discover,maestro,solo" accept_via_paypal="paypal" coupon="" accept_coupons="0" default_country_code="" captcha="0" /]

Hi Andres,

This is caused by some conflicting JavaScript code, possibly introduced by another plugin or by your WordPress theme.

To figure out which one is causing the problem, we recommend disabling all plugins except s2Member and switching to the default WordPress theme (TwentyEleven). If you’ve already tried disabling plugins with Plugin Organizer, there’s a good chance the problem is with your WordPress theme and in that case we would recommend that you contact the theme developer.
