/************************************************************
This script is for form validation to determine if all fields
have been filled out and if the email address supplied is of
valid syntax. If all statements return true then the form
is emailed to the specified recipient.

This script's main feature is that is replicates your form
for people if they missed a required fields. Any and all
fields that are missed show another form field, and those
that have been done properly show as normal text.

You will have to configure this to suit your needs. You will
also have to make sure that any input field names and hidden
field names reflect what you have on your form.
