Mandatory Check Script

Mandatory Check Script

Hello.

I'm having an issue where it appears the mandatory check script for my forms is not working. The lead submission successfully fires all of the right actions - auto response email, auto entry into CRM, etc. On the web page it's self, when the form is filled out, submission is being allowed even when required fields are not filled out. Can someone assist? The form is located at  http://www.quickhomefinancing.com/forms/purchase. As an FYI incase it makes a difference, the Zoho Sales IQ script is also included, however that functionality is not completely set up. In fact, because I'm still on a trial version, it appears the sales IQ has been disabled but the system will not let me remove it from the form functionality. Is this causing my problem?

Thanks!
Lori
