A little help with an If - Then statement - 5/14/2004 12:43:41
I am passing parameters through a hyperlink from a results page to a page that I want to compare the parameters and then redirect. These parameters include two numbers. I am trying to do this.
IF 1stvalue => 2ndvalue THEN response.write ("session is full") Else show form.
 I am not able to put it all together to complete this task. Thanks for your help.

First, are you sure the parameters are making it through? If so, you should see them in the URL. Assuming they are, then something like this:
In the body just before the form, paste this:
<%
If Value1 >= Value2 Then
Response.write "Session is full."
Else
%>
Then after your form, enter:
<%End If%>
That should work.

Unfortunately I don't think like either of you yet!
I pasted this before any code:
<%
IF CntOfAttendees=> Seats THEN
response.write ("session is full")
ELSE%>
and this after all code:
<%END IF%>
No matter what the values are the page displays "Session is Full" and never displays the form. The values are passing into the URL for this page.
Is there a format for the values that I need to use?

Try this in place of the first snippet above.
<%
Dim CntofAttendees, Seats
CntofAttendees=CInt(Request.QueryString("CntofAttendees"))
Seats=CInt(Request.QueryString("Seats"))
IF CntOfAttendees=> Seats THEN
response.write ("session is full")
ELSE%>
Also, I am not positive you can put the snippet at the very beginning of the page. I would suggest you put it just before the <form> tag.

The CntOfAttendees value comes from a COUNT in db and the seats value is from a table and is a number.

Generally speaking, if you're going to use VBScript variables outside the current code block (the <% and %>), then you should DIM them. If not (and IIRC) the variables only apply to the local block.
It's also good practice to define all variables. I have had circumstances where I've used the same variable name twice. By DIMming them, VBScript will tell me that I've already defined it and hence avoid the problem.

If that still does not give you the results you expect, debug it with a response.write:
