asp三级联动问题

我使用asp三级联动菜单修改产品的时候，点击产品之后就一直卡住不动，等了很久提示脚本超时，服务器上的脚本超时时间我已经调到了几万了还是一样，添加产品的时候使用的也是同样的代码，差别就是修改的时候要读出产品的初始值，主要代码如下，请大家帮帮忙，看看到底是哪里出现问题，是不是脚本程序有问题还是三级联动很难避免这个现象
<script language = "JavaScript">
var onecount;var threecount;onecount=0;threecount=0；
subcat3=new Array();
<% count = 0
do while not rs3.eof %>
subcat3[<%=count%>] = new Array("<%= trim(rs3("nclass"))%>","<%= rs3("lclassid")%>","<%= rs3("nclassid")%>");
<%count = count + 1
rs3.movenext
loop
rs3.close%>
threecount=<%=count%>;subcat = new Array();
<% count = 0
do while not rs.eof %>
subcat[<%=count%>] = new Array("<%= trim(rs("lclass"))%>","<%= rs("ID")%>","<%= rs("lclassid")%>");
<% count = count + 1
rs.movenext
loop
rs.close%>
onecount=<%=count%>;
function changelocation(locationid)
{ document.myform.lclassid.length = 0;
var locationid=locationid;
var i;
for (i=0;i < onecount; i++){
if (subcat[i][1] == locationid){
document.myform.lclassid.options[document.myform.lclassid.length] = new Option(subcat[i][0], subcat[i][2]); } }
changelocation3(document.myform.lclassid.options[document.myform.lclassid.selectedIndex].value) }
function changelocation3(locationid) {
document.myform.nclassid.length = 0;
var locationid=locationid;
var i;
for (i=0;i < threecount; i++) {
if (subcat3[i][1] == locationid){
document.myform.nclassid.options[document.myform.nclassid.length] = new Option(subcat3[i][0], subcat3[i][2]);} } }
</script>

死循环了。
