关于二级联动下拉列表的问题，请大家帮帮忙

数据表：
depart表(dept_id,dept_name)
staff表(staff_no,staff_name,dept_id)
表中都有数据

代码如下：
<!--#include file="conn.asp"-->
<%     
  set rs=server.createobject("adodb.recordset")   
  rs.open "select * from staff",conn,1,1
%>   
<script language="JavaScript">   
  var   onecount;   
  onecount=0;   
  subcat=new Array();   
  <%   
   count=0
    do while not rs.eof     
  %>   
  subcat[<%=count%>]=new Array("<%=rs("staff_name")%>","<%=rs("depart_id")%>","<%=rs("staff_no")%>");
  <%              
                  count=count+1   
                  rs.movenext   
                  loop   
                  rs.close
  %>   
   
  onecount=<%=count%>   
   
  function changestaff(values)   
          {   
          document.form3.staff.length=0;     
   
          var   values=values;   
          var   i;   
          for   (i=0;i<onecount;i++)   
                  {   
                          if   (subcat[i][1]==values)   
                          {
          document.form3.staff.options[document.form3.staff.length]=new Option(subcat[i][0],subcat[i][2]);   
                          }                  
                  }   
                    
          }           
  </script>
  
  <form action="kaoqin_query_staff.asp" method="post" name="form3">
  <label>请选择部门：</label>
  <select name="deptment" size="1"  >
  <option >未选定部门</option>
    <%
set rs0=server.CreateObject("ADODB.recordset")
    sql0="select * from depart"
    rs0.open sql0,conn,3,1
while not rs0.eof
response.Write("<option value="&rs0("dept_id")&">"&rs0("dept_name")&"</option>")
rs0.MoveNext
wend
%>
  </select>
  <label>请选择员工：</label>
  <select name="staff" size="1">
  <option name="">未选定部门</option>
   </select>
  <input type="submit" name="submit3" value="查询">
  </form>
结果在staff中一个选项没有
