Hi all, I have small js that is being called when a radio button is clicked. I need that to set a cf session var which will have the radio value so that when the page refresh it will remember what is selected...

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<cfif cgi.PATH_TRANSLATED CONTAINS 'index.cfm'>
<cfoutput>
<META HTTP-EQUIV="refresh" content="60;URL=http://#HTTP_HOST#/NEA/index.cfm?location=ALL">
</cfoutput>
</cfif>

         <script type="text/javascript">
         function select_location(select_me){
          window.location ="index.cfm?location=" + select_me.value;
         }
         </script>
         <input <cfif url.location eq "NM">checked="checked"</cfif> type="radio" name="location" id="NM" value="NM" onClick="select_location(this);"><label for="NM">NM</label>
         <input <cfif url.location eq "SM">checked="checked"</cfif> type="radio" name="location" id="SM" value="SM" onClick="select_location(this);"><label for="SM">SM</label>
         <input <cfif url.location eq "BQ">checked="checked"</cfif> type="radio" name="location" id="BQ" value="BQ" onClick="select_location(this);"><label for="BQ">BQ</label>
         <input <cfif url.location eq "MV">checked="checked"</cfif> type="radio" name="location" id="MV" value="MV" onClick="select_location(this);"><label for="MV">MV</label>
         <input <cfif url.location eq "SI">checked="checked"</cfif> type="radio" name="location" id="SI" value="SI" onClick="select_location(this);"><label for="SI">SI</label>
         <input <cfif url.location eq "BR">checked="checked"</cfif> type="radio" name="location" id="BR" value="BR" onClick="select_location(this);"><label for="BR">BR</label>
         <input <cfif url.location eq "HV">checked="checked"</cfif> type="radio" name="location" id="HV" value="HV" onClick="select_location(this);"><label for="HV">HV</label>
         <input <cfif url.location eq "ALL">checked="checked"</cfif> type="radio" name="location" id="ALL" value="ALL" onClick="select_location(this);"><label for="ALL">ALL</label><br>

JavaScript runs on the Client. ColdFusion runs on the server. They do not talk to each other or share memory.

The only way to get data from the client to the server is to make a request. The only way to get data from the server to the client is to respond to a request.

You can make that request by submitting a form either in the get or post scope.

You can make that request by sumitting a request with the xmlHTTPrequest() function, commonly called AJAX.

But somehow or the other you have to make a request.
