If Then

I am designing a small .asp (classic) application, I am connecting to
a Access 2k database via ADO to retrieve data. I have a number
variable's that contain text that is posted from a previous screen

AMPM = Request.Form("AMPM")
AMPMDate = Request.Form("AMPMDate")
halfday = "(" & AMPM & "," & AMPMDate & ")"

I then compose a CDOSYS email and send the value of the variable in
the .HTML body of the email

..HTML = "Number of Days" & halfday

What I would like to do is only display the value of the halfday
variable if it contains a value. I was thinking along the lines of

If halfday = Null Then
halfday = ""

Else

halfday = halfday

End if

I know this does not work, but it gives an idea of what I am trying to
achieve.
Any help would be appreciated.

Regards

This will never be true. Comparisons to Null always result in Null. You
probably mean:

If halfday Is Null Then

However, this will also never be the case at this point because in your
previous statements, you assigned values to halfday. I think what you
intend to do is something like;

If AMPM = "" And AMPMDate = "" then
halfday=""
Else
halfday = "(" & AMPM & "," & AMPMDate & ")"
End if

Your VBScript getting a bit rusty Bob?

If IsNull(halfday) Then

The Is keyword in VBScript tests the type of an object (via the
QueryInterface method).

Bob's VBScript may/may not be a bit rusty (I am not qualified to
judge, hence my question) but it worked for me!
Thank you both very much for your help.
