Cannot Click in Form Field

I’ve created a contact form in Flash CS3, using AS3. I copied and pasted the fields, changing the instance name of each (name_txt, email_txt, etc.). 3 of the fields work as expected, but I am unable to click in two of them and can only navigate to them by tabbing from one of the other fields. This is especially annoying when the validate function tells the user to enter an email address, and they can’t click in the email address field. Any help would be much appreciated!

Here’s a link to the form:http://billiondollarmentoring.com/new/contact.php

The Phone and Email fields aren’t working properly, everything else is.

Any help would be much appreciated - Thanks in advance!
