求助:我是新手,请帮忙看以下ASP出错是什么原因?

[kendy81]

<!--#include file="conn.asp"-->

<%

on error resume next
t1=request("t1")
t2=request("t2")


'list1=request("list1")
'kkk=request("file1")
'response.write kkk

set conn=server.createobject("adodb.connection")
conn_str = "DBQ=" + server.mappath("db1.mdb") + ";DefaultDir=;DRIVER={Microsoft Access Driver (*.mdb)};"
conn.open conn_str
sql="insert into plist(pid,pass) values('"&t1&"','"&t2&"')"
'response.Write(sql)
'response.end
conn.execute sql

set rs=server.createobject("adodb.recordset")
'sql="select top 1 pid,pass,a3 from plist order by id desc"
'rs.open sql,conn,3,2
'response.Write(rs("id"))
'response.End()
rs("pid")=rs("id")
rs.update
rs.close
set rs=nothing

conn.close
set conn=nothing
'response.redirect "upfilein.asp"
response.Write("<script language=JavaScript>alert('Add client successful !');window.location.href='list.asp';</script>")

%>

我是新手,不知错在哪一行,该如何调试呢?我没有装PWS,听说它可以进行调试是吗?
