I use multiple tab forms in HTML and use javascript and PHP to send all values to an email. Please review the code below. I receive this email:

Zipcode: Question1: Question2: Question3:

I think think there is some javascript or PHP errors. I'm using forms in multiple tabs and send value to an email on submit.
