同一个页面里能用两个联动菜单吗？

[htpower]

<script language=JavaScript>
<%
dim sql,i,j

set rs=server.createobject("adodb.recordset")
sql="select * from ck_rootclass order by id desc"
rs.open sql,conn,1,1
tmpid=rs("id")
%>


var selects=[];

selects['#']=new Array(new Option('请选择分类','#'));



<%
for i=1 to rs.recordcount
%>


selects['<%=rs("id")%>']=new Array(
<%


set rsk=server.createobject("adodb.recordset")
sql="select * from ck_bigclass where rootclass="&rs("id")&" order by id"
rsk.open sql,conn,1,1
if rsk.recordcount>0 then
for j=1 to rsk.recordcount
if j=rsk.recordcount then
%>


new Option('<%=trim(rsk("ck_bigclass"))%>','<%=rsk("id")%>'));


<%else%>


new Option('<%=trim(rsk("ck_bigclass"))%>','<%=rsk("id")%>'),


<%
end if
rsk.movenext
next
else
%>
new Option('暂无类型','0'));


<%
end if
rsk.close
set rsk=nothing
rs.movenext
next
rs.close
set rs=nothing%>
//new Option('','0'));

<!--//////////JavaScript控制联动///////////-->
function chsel(classn,bigclass){
with (document.s2){
if(classn.value) {
bigclass.options.length=0;
for(var i=0;i<selects[classn.value].length;i++){
bigclass.add(selects[classn.value][i]);
}
}
}
}
</script>

为什么出来的效果里不能选择同一个分类下的二级分类？空白的~头晕ING~
