// 	<script language="JavaScript" src="Validation.asp" type="Text/JavaScript"></script>
//
//== Event Handler =======================================================================================================================//
//
// 	Include the following event handler to activate the form validation functions.
//
// 	onSubmit/onClick="return(Validate(this.form.name));"
