asptoday_discuss thread: Checking value of hidden field with Request.Form

Hi,
I can successfully get data from a previous form using Request.Form.
Here's my code:
I get the value from previous form:
var From1 = Request.Form("From1");
Just after my BODY tag I write:
<%if(From1==""){%>
<script Language="Javascript">
<!--
alert("You have not answered all the question for this section! You will
now be redirected to the first
architecture question");
// -->
</script>
<%}%>
The problem I'm having is that when From1 has no value. I want the script
below to run, but I can't
ever get it to work.
I've also tried:
From1==null
From1==false
From1==0
if(From1!=null){}else{...}
None of these work! Whats the correct why to check the value of this
variable?
Thanks in advance.

Try this...
If Request.Form("From1") Is Nothing Then
Else
End If

Hi Kevin,
Are you sure the NAME attribute in the hidden field in your previous form is
set to "From1"?
<input type="hidden" name="From1" value="3.141615">
That may be why it's not pulling the value in your JavaScript.
HTH,
Jason
