check for QS or posted value and place value in variable

Hi

Can someone help?
I have a validation(hidden) page which retrieves data and submits it and then response.redirect's to another page called process.asp. It passes the id as a querystring. (prefereably I'd like it to be passed by post method as it's more secure but guess not possible?)

The process.asp page now needs to check for this querystring and *also* posted values coming in from other  pages. So there are values coming in from 2 types of methods but only one at a time. So either req.form will be empty or req.qs will be empty.
I need to check:
- are both empty? then print this page
- if the qs isn't empty then put it in strid else if request.form isn't empty then put that value in strid.
How do I make sure that strid is not empty?

I am posting the relevant code. It may be easier for you to see as I'm even having difficulty explaining it! You will see 3 links that use the post method. On the pages they post to, there is a back button which posts the value back to the process page. That is why I need to check for values posted. I am trying to avoid using QS's.

Thanks. Appreciate it.

<% 'if value passed by qs or form then means that user has completed step 1 so mark step 1 as completed.

Well, one problem I see here is that you cannot say:

If Request.Form = "" Or Request.QueryString = "" Then

You have to say it like this (or something like this):

If Request.Form("<field name>") = "" Or Request.QueryString("id") = "" Then

If you are using the Request.Form or .QueryString methods, you HAVE to be calling the value of some field or string name.
