Poll with javascript

[SusieG]

Hello

I'm trying to add a poll to my website. Once you have made your selection you can never get back to the voting options.

In this script it has a facility to prompt users that you can only vote once but I can't get it working.

Can anyone advise me? I have posted the code below.

Thanks
Susie



<CFPARAM NAME="Client.Voted" DEFAULT="False">
<CFPARAM NAME="action" DEFAULT="">

<CFIF IsDefined("rdo_AnswerID") AND Client.Voted EQ "False" AND action EQ "vote">
<CFQUERY DATASOURCE="#DataSource#">
UPDATE tblAnswers
SET Votes = Votes + 1
WHERE AnswerID = #rdo_AnswerID#
</CFQUERY>
<CFSET Client.Voted = "True">
<CFLOCATION URL="#HTTP_REFERER#">
<CFSET Client.Voted EQ "True" AND action EQ "vote">
<SCRIPT LANGUAGE="JavaScript">alert("You are only allowed to vote once.");</SCRIPT>
<CFLOCATION URL="#HTTP_REFERER#">
</CFIF>
