Validate SalesForce web-to-lead form on Facebook page

Hello Freelancers. I need to get form validation for a SalesForce web-to-lead form on a Facebook page. This is the current static page with the code (the data gets passed to a SalesForce account) [login to view URL] This is the current functional JS file [login to view URL] Here is a resource for getting started with FBJS and validation (this example only accounts for a checkbox, but the error message gets displayed on the Facebook page- that's what I need): [login to view URL] In order to manage this, it would be optimal if the winning bidder can post my existing page ([login to view URL]) to an existing FBook page (maintained by the winning bidder) for testing and approval. Thanks.
