There are a number of ways to do this. Here's one that will cope with the
fact that one page posts to another.
ExampleForm.asp
<form method="post" action="Action. asp">
<p>Enter First name: <input type="text" name="FirstName "
value="<%=Sessi on("FirstName") %>"></p>
<p>Enter Second name: <input type="text" name="SecondNam e"
value="<%=Sessi on("SecondName" )%>"></p>
<p><input type="submit" name="submit" value="Click Me"></p>
Action.asp
<%
Dim x, boolValid
For Each x in Request.Form
Session(x) = Request.Form(x)
Next
boolValid = True
'Validate form values
If 'any test fails Then
boolValid=false
End If
If boolValid = false Then Response.Redire ct("ExampleForm .asp")
%>

Mike, do you mean that I should then repopulate the form from the Session(x)
if I come back to the first page?
Isn't it too much waste of server memory to use session variables for normal
data between pages?
If someone uses the back button in the browser, all the fields are still
there. Couldn't I do the same thing with asp code?

You can't rely on the back button maintaining form state. The back button
belongs to the browser, and as such is outside of the control of an asp
developer.
Personally, I get pages to post to themselves in the vast majority of cases.
I usually do this kind of thing:
<%
Sub ShowForm
%>
<form method="post" action="">
<p>Enter First name: <input type="text" name="FirstName "
value="<%=Reque st.form("FirstN ame")%>"></p>
<p>Enter Second name: <input type="text" name="SecondNam e"
value="<%=Reque st.Fom("SecondN ame")%>"></p>
<p><input type="submit" name="submit" value="Click Me"></p>
<%
End Sub
If Not IsEmpty(Request .Form("submit") ) Then
'Form posted
'validate values
'if validation fails, show form
Call ShowForm
Else
Success
Else
Call ShowForm
End If
%>
But of course, some forms need more than one page. If you think that using
session variables will be too much for your environment, you can use a
database, text files, hidden fields etc.

Yes it works now with hidden fields, but I have found it is necessary to use
a submit button to get them back to page1. They do not appear, when I try to
do it in the background with Response.Redire ct "page1,asp"
Is there a way to catch the hidden fields without a button?
