$strLink = urlencode("updateChart(" . $intYear . "," . chr(34) . $ors['Country'] .  chr(34) . ");");
$strXML .= "<set label='" . escapeXML($ors['Country'], $forDataURL) . "' value='" . $ors['Average'] . "' link='" . $strLink . "'/>";

And something like this in ASP:

'Generate the link
   strLink = Server.URLEncode("updateProductChart(" & intYear & "," & oRs("MonthNum") & "," & ors("CategoryId") & ");")
   'Append data
   strDataXML = strDataXML & "<set value='" & oRs("Total") & "' link='" & strLink & "'/>"

I'm still getting the same error. "COHASH7" is undefined.

string coIDcoded = "COHASH7";
string strLink = Server.UrlEncode("updateChart("+coIDCoded+");");
this.strXMLDoc += "<set value='" + coAMT.ToString() + "' name='" + coIDCoded + "' color='" + colorArray[colorCount] + "' link='"+strLink+"'/>";

Thanks.

Got it working. Thanks for your help. Some tricky url encoding did the job.

Thanks
