How can I get this form to actually submit, when someone clicks the submit button?

I created 2 other forms on my website - the portrait session agreement and wedding/special event agreement - that work perfectly fine. But when clicking on the submit button on the contact form, it says "please wait" and nothing happens. All forms have been embedded the same exact way. Please help

There is a conflict between jquery lines of code and the form's code. To resolved, please replace form's current embedded code, by the iFrame version
