//FORM SCRIPTS
/*
This script simply tests that required fields have had data entered withn them.  It does not validate the data within those fields.
Call is in this format:

 checkForm('formname','fieldname.text,Field Label,1||fieldname.radio,Field Label,1||fieldname.select,Field Label,1');

That's a "||"-delimited list for each field; within each of those, a ","-delimited list for fieldname (with a ".select" appended if it's a <select>, a ".radio" appended for <input type="radio">, a ".email" for email-address validation, and finally, ".text" for <input type="text"> fields), label name for error message, and a "1" if you can focus() on the field--otherwise pass a 0, the script will not attempt to auto-focus on the field after the error.
