修改

 我想问：我在用ASP做修改这个功能的时候，老是修改不了，我检查了没有哪里错误，我不晓得哪里出错拉请帮帮我吧：


<!--#include file="conn.asp"-->
<!--#include file="char.asp"-->
<%
if session("AdminName") = "" then
response.redirect "error.htm"
end if
%>
<%
name2=HTMLEncode(trim(request("cpbh")))
if name2="" then
   response.write "<script language='javascript'>"
   response.write "alert('对不起，请您商品编号!');"
   response.write "history.go(-1);"
   response.write "</script>"
   response.end
end if

name1=HTMLEncode(trim(request("cp_name")))
if name1="" then
   response.write "<script language='javascript'>"
   response.write "alert('对不起，请您商品名称!');"
   response.write "history.go(-1);"
   response.write "</script>"
   response.end
end if

name3=Formatnumber(request("cp_price"),2)
if name3="" then
   response.write "<script language='javascript'>"
   response.write "alert('对不起，请您商品价格!');"
   response.write "history.go(-1);"
   response.write "</script>"
   response.end
end if

content1=HTMLEncode(request("cp_jieshao"))
id=request("id")

set rs=server.createobject("adodb.recordset")
sql="select * from cp where id="&request("id")
rs.open sql,conncp,1,3
rs("cpid")=name2
rs("cpname")=name1
rs("price")=name3
rs("jieshao")=content1
rs.update
rs.close
conn.close 
set rs=nothing
set conn=nothing
%>
<script language=javascript>
alert("修改成功！");
window.location.href="cp_index.asp";
</script>
