I got it somewhat close by using a function RegExp and then applying that to the SiteId field, however the way the page is written if a user selects or pastes a value in any of the other 4 fields VendId, PONbr, etc. then the data is returned to the page regardless of the SiteId being blank.

Any ideas?

<%@ Register TagPrefix="uc1" TagName="MenuBar" Src="MenuBar2.ascx" %>
<%@ Register TagPrefix="uc1" TagName="PV" Src="PV.ascx" %>

<%@ page language="vb" autoeventwireup="false" inherits="ReQlogicFW.Receipt, ReQlogicFW" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<%@ Register Src="PVDate.ascx" TagName="PVDate" TagPrefix="uc2" %>
