[Plugin: Visual Form Builder] Form not submitting

Hi. I am desperately trying to find a form plug-in which works with the Unite theme by Parallelus. I’ve tried several form plug-ins and either the validation doesn’t work or as the case with the Visual Form Builder, the form is not submitting. When I complete the form and click Submit, the page just refreshes and an email is not sent and an entry is not made in the WordPress database. I noticed someone posted about this problem who is using this same theme about three months ago and the author said the value of the Submit button had been changed by the theme. Can you tell me what the value should be and how to change it back? I was excited for this plug-in because it said no programming was required but now it’s looking like it’s not that easy.

My form: http://www.ofosa.org/wordpress/?page_id=406.
My theme: http://themeforest.net/item/unite-wordpress-business-magazine-theme/90959
