Hi Tom,
FYI, that's VB.NET, not VBScript (aside from syntax, the two are very dissimilar).
Are you thinking of the RequiredFieldValidator? If so, you could use one like this:
<ASP:RequiredFieldValidator
ControlToValidate="txtEmail"
Display="Static"
ErrorMessage="Required"
runat=server />
Cheers,
Peter

Hello again,
Still working on my form and have a question. I'm picking off the user's e-mail address from the
form like so (VB Script):
Dim objMM as New MailMessage()
objMM.From = txtEmail.Text
However,this is not required. But if they don't fill it in I get an error since the mail object (I
think) requires a sender.
How can I test objMM.From to see if it is blank, and if not supply a no-reply email like
(no-replay at somewhere.com) so the email fires off?
Also, I thought I saw somewhere there was a simple way to require fields in ASP.Net...
Thanks
Tom
