Form Method=Post => how to process options ?

[leifoet]

The structure of the main menu in the current application is as follows:

=> Choice
radiobutton 1 => 'select multiple' = link to continuation_for_multiple.asp
radiobutton 2 => link to continuation file2.asp
radiobutton 3 => link to continuation file3.asp
radiobutton 4 => link to continuation file4.asp

=> Code form
<form name = "Member List" onSubmit = "return validation (this);" METHOD = "POST" ACTION = "continuation_for_multiple.asp">

=> Submit
<INPUT TYPE = "submit" VALUE = "Execute">


In this case : the Request.Form("A_Id") are only 'delivered' to "continuation_for_multiple.asp"

My problem
How can I get the (specific) Request.Form("A_Id") of radio button 2 are delivered to continuationfile2.asp
and the (specific) Request.Form("A_Id") of 3 to continuationfile3.asp and the (specific) Request.Form("A_Id") of 4 to continuationfile3.asp ?

Probably with 'if' in <form name ...> but how / where to insert this code? - Is this the right method?

Thanks for tips.
