Problem - Parsing information using onchange in two select fields

[please-answer-here]

Scenario:

I'm having an asp page with a form with an action pointing to itself. The
reason for that, it that the asp page depending on changes in any of two
select fields with data from 2 different databasetables are going to
populate a third select field.

what I have done is something like:

response.write("<select size=""1"" name=""fabrikat""
onchange=""document.forms[0].submit()"" >")
response.write("<select size=""1"" name=""type""
onchange=""document.forms[0].submit()"" >")

what I very much would like was a way that I in the asp page when it got
reloaded could check which of the "select" fields have generated the submit.
If I had used submit buttons I could have used a querystring, but as the
reload of the page sholud happen transparent to the user it is out of the
question

regards
Henning

response.write("<select size=""1"" name=""fabrikat""

onchange=""document.forms[0].submit()"" >")
response.write("<select size=""1"" name=""type""
onchange=""document.forms[0].submit()"" >")

what I very much would like was a way that I in the asp page when it got
reloaded could check which of the "select" fields have generated the
submit.

Try
<input type="hidden" name="WhichSelect">
<select size=""1"" name=""fabrikat""
onchange="document.forms[0].WhichSelect.value="fabrikat";document.forms[0].submit()">

and for the other one:
onchange="document.forms[0].WhichSelect.value="type";document.forms[0].submit()">

Hope that helps
