/**** form validation script ******/

/********** INSTRUCTIONS ******************

	This script can be used with any form to validate form fields. The syntax to check
	whether or not a field has a value is: 
	
	if(!<fieldName>.value){forgot += ' - Your message\n';}
	
	In the above example you would replace "<fieldName>" and "Your message" with the
	appropriate field name and message respectively.

	IMPORTANT NOTE: Make sure to uniquely name your form fields
