//RequiredVerify.js

/*
This file checks that all required fields are completed in a form.

place onSubmit="return submitForm('form_name');" in your form header
be sure to pass the form name

also place a hidden input whose value is a list of all the required fields in your table,
named requiredFields

note: if you have two fields with similar names (ie: Title, and JobTitle) - 
if Title is set to be required - JobTitle will also be flagged as required.  
Therefore, use more descriptive naming.

No Spaces in your list - if you put in spaces it will not work!!
ex: <input type="hidden" name="requiredFields" value="LastName,FirstName">
