晕，密码对与错都说密码错误
先拜个晚年
，祝各位前辈狗年快乐
进入正题，呵呵，下面是代码，为什么验证密码时无论对与错都说错误呢？？
谢谢
<!--#include file="../com/conn.asp"-->

dim txt_zj
dim txt_pw
txt_zj=request.Form("txt_zj")
txt_pw=request.Form("txt_pw")
if trim(txt_zj) &"x"="x" or trim(txt_pw) &"y"="y" then
response.Write("<script>alert('证件名或密码不能为空，请检查输入信息')</script>")
response.write ("<script>window.location='../main_index.asp'</script>")
else
dim strsql
dim rs
strsql="select * from usertb where user_num='"&txt_zj&"'"
set rs=server.CreateObject("adodb.recordset")
rs.open strsql,conn,3,3
if rs.recordcount=0 then
response.Write("<script>alert('无此证件号，请检查输入信息')</script>")
