//PURPOSE: client-side form field validation code
//	This set of function are general includes for validation
//	They are designed in pairs the validation and the event function
//	the event function will call the validation with the event src
//PARAMETERS:    
//CALLED FROM:
//CREATED:                   
//MODIFIED: 12/21/99    new email check and added validCurrency()
//MODIFIED: 01/27/99    modified all
// 04/20/2000	- min pass length is now 6chars
// 10/04/2000 - ValidPhone()
// 11/09/2000 - ValidPhone() modified to allow "+" characters	
// 11/30/2000 - new function ValidState_Country()
// 01/31/2001 - bug fix in ValidCurrency() and ValidNumeric() functions
// 03/07/2001 - changes to ensure compatibility with WebTV browsers:
//            - replaced extended properties "Trim" and "toSimpleForm"
//   because WebTV does not support "Object.prototype()"
// 04/27/2001 - added NoQuotes() function
// 06/05/2001 - modified ValidPhone() function to allow "x" and "X"
// 06/27/2001 - modified ValidCurrency() and ValidNumber() to give more
//   instructions to users
// 07/10/2001 - ValidCurrency() - check if value fits the range allowed 
//   for money data type
// 11/12/2001 - changed "must not" to "may NOT" in alerts
// 01/04/2001 - modified ValidEmail() function to prevent users from 
//   entering "," and ";" characters
// 01/10/2002 - modified ValidEmail() function to prevent users from 
//   entering ">" and "<" characters
// 03/27/2002 - modified ValidPhone() to say "Phone may contain only 
//   numbers 0 to 9 and ()/-+xX"
// 04/26/2002 - added ValidLastName() function
// 06/27/2002 - changed the warning messsage:
//                “XXX must be at most Y characters long.” to:
//                “XXX may not be more than Y characters long.”
// 12/16/2002 - added ValidUsername and ValidPassword functions
// 06/26/2003 - added ValidZip_USA() function
// 07/24/2003 - modifed ValidState_Country() to use new state_region_code
// 09/08/2003 - bug fixed in ValidCountryStateRegionSelection()
// 02/15/2005 - added ValidWebPageName() function
