/* Modification Notes: 02-21-03

This original script was taken from this page:
	http://thesamplecenter.com/register/register_frame.cfm?TID=162103105716100295342&SID=1000&CID=0&UID=0&LAT=211002160357


The modifications were added so that this script could be an external 
file that validated two forms: "form_sample_center.htm" and "form_viewbook.htm".
These two pages are associated with the landing page, "www.i2byinterface.com/<name_of_landing_page.htm>".

Each form is numbered on the HTML page with an embedded javascript:
	form_sample_center.htm corresponds to form_num == 1
	form_viewbook.htm corresponds to form_num == 2
	
	
The validation script checks to see what form_num it is validating before executing the logic.
Some variables were added to set flags for the modified logic.  They are commented.
