List Box Selecting Resets Client Variable

[ClayD-B411TV]

Does anyone know how I can reset a client variable, client.afid, after a user selects a value from a list box? Pretty much onClick the page will refresh I guess and the client.afid will be changed to the list box selection. I don't know a ton about javascript.

sorry, left the code out.

<cfif IsDefined(client.afid) AND IsDefined(client.custid)>
<select name="client.afid" onclick="location.reload();">
<cfloop query="qrySelectafid">
<option value="#qrySelectafid.thirdParty_id#">#qrySelectafid#</option>
</cfloop>
</select>
</cfif>

It's easier for you and freindlier to the user if you do all this stuff when the form is submitted.
