一个判断语句

请问各位大侠这个判断写错了吗?不论De_name是否为空他为什么一直显示的是下拉列表呢?

De_name 文本存人名

   sub showDe_name()
          set rs=server.createobject("ADODB.Recordset")
          sql="select * from [BJ_Business] "
          rs.open sql,conn,1,1
          if De_name="" then
          response.Write "<form name=""form1"" method=""post"" action="""">"
          response.write "<label>"
          set rs_C=server.createobject("ADODB.Recordset")
          sql2="select * from [CRS] where SmallClassID=2"
          rs_C.open sql2,conn,1,1
          response.Write "<select name=""Cid"" id=""Cid"">"
          do while not rs_C.eof
          response.Write "<option value=""&rs_C(Cid)&"">"&rs_C("Cname")&"</option>"
          rs_C.movenext
          loop
          rs_C.close
          'set rs_C=nothing
          response.Write "</select>"
          response.Write "</label>"
          response.write "<label>"
          response.Write "<input type=""submit"" name=""button"" id=""button"" value=""确认"">"
          response.write "</label>"
          response.write "</form>"
          else
          response.Write rs("De_name")
          rs.close
          set rs=nothing
          end if
    end sub
