Table querying in ASP

This is a simple question, so sorry for my newbieness. How do I query
data about a html table? Specifically I want to know how many columns
there are currently. I thought something like this would have worked:

<% NumCols = Request("Columns") %>

But it doesn't. Any help greatly appreciated. Thanks....

ASP knows nothing about the html in the submitting page. All it can see are
the name/value pairs submitted by the form, the names coming friom the name
attributes of the elements in the form.

What you can do is use a hidden field in the form, and
a) if the table is generated by server-side code, add a line to the
server-side code to set the value of the hidden field to the number of
columns
b) if the table is generated using client-side code, use client-side code to
set its value to the number of columns in the table, perhaps in the onsubmit
event.

A better group for ASP server-side questions would be
microsoft.public.inetserver.asp.general.
