asp.net vb email

Hello,
I have email script, and it works fine in the sample page.
However, if I copy and paste the script in other page, it stop working.
It doesn't give me any error message, and I have no idea what's causing it.
IDs are the same in both pages.
May be it's conflicting with other script in code behind VB.

Any idea?

Thank you.

Did you try setting breakpoints and see if it is not hitting any Catch?
set breakpoints at
Try and all Catch and then debug ....Or add
Respose.Write(smtpExc.ToString) and
Respose.Write(ex.ToString) to your ending catch blocks..

Hello, I did response.Write and got following message.

System.Net.Mail.SmtpException: Failure sending mail. ---> System.InvalidOperationException: Asynchronous operations are not allowed in this context.
