Reloading a select box

Hi there, I've got a little question...

I want a dropdown box that displays a table with two coloums. One is text, the other one's a date.

I've done this with:

            <cfloop query="auftrag_filter">
            <cfoutput><option value="#auftrag_filter.id#">#bezeichnung# (#DateFormat(termin_datum,'dd.mm.yyyy')#)</option></cfoutput>
            </cfloop>

that works, but the problem I have now is that I would like the the page to reload after I make a selection. Tried it with a javascript but doesn't work so far...

<script language="javascript" type="text/javascript">
<!--
function reloadPage() {
      window.location.href="betreut_filter.cfm?auftrag_id="+document.getElementById("auftrag_auswahl").value;
}
-->
</script>

<cfquery name="auftrag_filter" datasource="mvs">
SELECT bezeichnung, termin_datum, id
FROM auftrag
ORDER BY bezeichnung
</cfquery>


            <cfif IsDefined('auftrag_id') >
            <select name="autrag_id" id="auftrag_auswahl" onchange="reloadPage();">
            <cfloop query="auftrag_filter">
            <cfoutput>
            <option value="#auftrag_filter.id#"  <cfif #URL.auftrag_id# is #auftrag_filter.id#> selected="selected"</cfif> >#bezeichnung# (#DateFormat(termin_datum,'dd.mm.yyyy')#)</option>
            </cfoutput>
            </cfloop>
            </select>
            <cfelse>
            <select name="autrag_id" id="auftrag_auswahl" onchange="reloadPage();">
            <cfloop query="auftrag_filter">
            <cfoutput><option value="#auftrag_filter.id#">#bezeichnung# (#DateFormat(termin_datum,'dd.mm.yyyy')#)</option></cfoutput>
            </cfloop>
            <option value="null" selected="selected">Bitte auswählen</option>
            </select>
            </cfif>

The result is now that when I start the page I have "Bitte auswählen" in the Box. After changing to any entry, the browser gives me the first value of the dropdown list back and not the selected one.

thanks for any help
