ASP下拉式菜单写法哪错了？请教大家

<!--  #include file="../db.inc.asp" -->
<table width="524" border="1">
<caption align=center> <h4>A表 </h4> </caption>
<tr>
    <td width="159" align=center>B
    <% set rst=Server.CreateObject("ADODB.recordset")
  rst.open aaa,conn,1,1 %>
    <select name="jufenjiekou" size="1">
    <% while not rst.eof %>
        <option value=" <% rst(1) %>">" <% =rst(1) %>" </option>
    <% rst.movenext
  wend %>
      </select> </td> 
  </tr>
----------------------
aaa是数据库表，有两个字段，取第二个字段的值放入下拉菜单中

<% set rst=Server.CreateObject("ADODB.recordset")
sql="select * from aaa"
  rst.open sql,conn,1,1 %>
