// Comments: page uses 1 form, contents are submitted to CARRIERS server, each carrier running their own cgi script.
//
// Assumptions: CARRIER'S server and cgi script are running;  
// 			 Correct path to cgi scripts are coded in variables below.
//			 Correct field names anticipated by the carrier's cgi script are coded below.
