QueryString issue

[DaveRook]

Hi

Can I check if a querystring is null (ie, doesn't exist) compared to one which is empty?

In 'English' I want the statement to say:

If the querystring is present but empty then
n = true
end

This is for a validation page. The issue I have is the querystring may or maynot be present in the URL.

if Request.QueryString("aaa") <> null AND Request.QueryString("aaa") = "" then
		n = true
end if	

Response.Write("The answer is " & n)

This doesn't work. I don't get a result at all. It's almost as if vbscript sees null and empty as the same thing.

Any ideas?

Dave

Sorry

There was another mistake else where on the page which affected the result. Sorry all, please ignore this post
