Hi, I'm quite new to programming, and I can't figure out the solution for this problem.
I have tried the examples on chapter 7 of the book (page 255) about the request and response objects.
the Request.QueryString.htm page will display normally, but, when I click the "submit" button, I get this message on the browser:

Holiday Response Form
Apache Active Scripting Runtime Error

Object required: 'Request.QueryString(...)'

Line #9, Char #3

When I got absolutely desperate trying to find out how to repair it, without success, I deleted the files and used instead teh ones downloadable from the book's downloads page, and i got exactly the same result.
Am I doing anything wrong?
Or is the fact that I'm using an Apache web server what is causing the problem?

Thank you very much in advance for your help.
Paco.

Well, this is a self-reply to my own question, but I'm going to post it because I think it may be useful to someone facing the same problem, or someone may find a way to improve it.
I have reached a partial solution to the problem, and I think that this is caused by how the Apache server handles ASP objects.
The problem was that if I typed Request.QueryString("HolidayLocation").Count=0 the server would send the message
Apache Active Scripting Runtime Error

Object required: 'Request.QueryString(...)'

Line #11, Char #2
But if I typed Request.QueryString.Count=0, then the answer changed. If I selected one city, it would give me the correct output, such as
We will send you details on Rome as requested.
If I selected more than one city, it would only "read" the first of them. For example, if I selected Madrid and Paris, the output would be
We will send you details on Madrid as requested, and If I didn't select any city, instead of the expected output, which should be
"We won't send you any details " I got this
We will send you details on as requested.
I could therefore select one city and get the correct output, but if I selected more than one or none at all the output would be somehow wrong.
The next thing I tried was to create a variable, strLocation, and give it the value of Request.QueryString("HolidayLocation") I then changed the code to look like this;
<%
  Dim strLocation
    strLocation = Request.QueryString("HolidayLocation")
    If strLocation = "" then
      Response.Write "We won't send you any details"
    Else
    Response.Write "We will send you details on "
    Response.Write Request.QueryString("HolidayLocation")
  End If
%>
 as requested.
By doing this, I could still only select one city, if I selected two or more, only the first would be recognised, but if I didn't select any city I would now get the correct output.
I guess I could mask the inconvenience by modifying the code in a way that only allow the user to select one city at a time, but that, of course, is not the objective of the exercise.
I would welcome any help on this, and also any insight on how Apache or any other server handles VBscript and ASP.
Thank you,
Paco.
