Hi everyone,
So I have a problem that is more difficult that it might seem at first
glance.  created.  Any help/a clever "duh" answer would be great as we've
spent more than 8 hours trying to get this working.

Please see the following thread for the full details:

"How To Add User's GUID To An Account Verification E-mail - E-mail Working,
Error In Retreiving GUID"

http://forums.asp.net/p/1172523

----
am receiving an error when I try to retrieve a newly (and
successfully...checked the DB) registered users GUID to include in an account
verification e-mail.  I am using the e-mail that is sent by the membership
provider, however I am adding an extra step for the user to verify their
account.  The e-mail works fine as long as I don't try and use the user's
GUID.  The verification of a user's account step uses a newly defined
placeholder (<% Username %> and <% Password %> are supported by default in
asp.net membership) in the .txt file that is the basis for the e-mail.  I can
get the placeholder to replace fine in the e-mail, however I get an error
when I try to include the user's GUID in the e-mail.

Here are examples:

Any help with fixing the error is appreciated.  Thanks!
