ASP, Forms and passing variables between frames

I am pretty new to ASP, I know VBScript reasonably well though. What I am trying to do is create a website with 2 frames. In the top frame, it asks for a year (from a selection box) and a week number (from a selection box). It should then display the dates relating to the selection and a button to process the request. When the button is clicked the bottom form then processes a SQL query based on the selection in the top frame and displays the info.

Now, my problem is when it comes to understanding ASP. With ASP, all the code is processed then the output is sent to the browser. How do you update variables or even pass them to other frames when the code has already processed?

I just need some pointers on the way forward to accomplishing the above.

Thanks

First off, don't use frames: they're annoying, ugly, and outmoded.

You can do something like this in asp, but it's going to require a round trip (or two) to the server.

The basic outline of the page (let's call it thispage.asp) would be something like

<html><head>[head stuff]
<%
dim yr, wk, i
yr = request.form("Year")
wk = request.form("Week")
'- if you use form method='get', then use request.querystring("Year")
if not isnumeric(yr) then
   yr = Year(date)  'or whatever else you want to use as a default
else
   yr = CInt(yr)
end if
'similar validation for wk
%>
</head>
<body>
<form method="post" action="thispage.asp">
<select name="Year" size="1">
<%
for i = Year(Date) - 2 to Year(Date) + 2
    response.write "<option value='" & i & "'"
    if i = yr then response.write " selected"
    response.write ">" & i & "</option>"
next
%>
</select> [similar code for week or date or whatever]
<input type="submit">
</form>
<%
If yr <> "" and wk <> "" Then
    '- look up stuff in database and output the desired data
    '- (this part will be much longer than this)
Else
    Response.Write "<p>Please make your selections above.</p>"
End If
%>
</body></html>

If you need to output form fields that are dependent on the user's initial year & week selections, then you're going to need more than one trip to the server, but it's still the same idea: set up the variables you're going to need, see if they have values, write out the form, and then if all the necessary variables have all the necessary values, then you can do your output stuff.
