数据库查询问题

<%
  name=Request.Form("student")
  id=Request.Form("student")%>
  <!-- #include file="include/conn.asp" -->
<%  Set rs = server.CreateObject("ADODB.Recordset")
    sql="select * from score where name='"&name&"'"
rs.Open sql,conn,1,1
Do While Not rs.eof     
              response.write (" <table> <tr> <td>&nbsp;&nbsp;学号:"&rs("id")&" </td>")
              response.write (" <td>&nbsp;&nbsp;姓名:"&rs("name")&" </td>")
response.write (" <td>&nbsp;&nbsp;语文:"&rs("yuwen")&" </td>")
response.write (" <td>&nbsp;&nbsp;数学:"&rs("shuxue")&" </td>")
              response.write (" <td>&nbsp;&nbsp;英语:"&rs("yingyu")&" </td> </tr> </table>")
                    
                    
  rs.movenext
  Loop
                    
  rs.close
  Set rs = Nothing
  
%>

为什么我这样查询会得不到结果呢。。。如在表单里输入“张三”提交后。。并没查到结果。。。虽然数据库的表里有“张三”
如果直接这样写。。可以显示结果的sql="select * from score where name='张三'"
