this:
<!--#include file="../WA_Universal_Email/CDONTS_NewMail_VB.asp" -->
<!--#include file="../WA_Universal_Email/MailFormatting_VB.asp" -->
needs to be changed to:
<!--#include virtual="/WA_Universal_Email/CDONTS_NewMail_VB.asp" -->
<!--#include virtual="/WA_Universal_Email/MailFormatting_VB.asp" -->
using the links relative to site should cause dreamweaver to write the include code that way automatically.
