帮忙看下哪个地方有问题啊？？？

response.end
end if

也不知道你具体遇到什么问题了。wmycom可能没看清你的代码，你的代码思路基本是正确的，不过也有些问题。我修改了一下：

<%
username=request.form("username")

sql="select * from data where username='"&username&"'and password='"&password&"'"
rs.open sql,conn,1,1

if rs.eof then
response.write "<script>alert('不存在此用户');history.go(-1);</script>"
response.end
end if
'密码对应
if rs("password")<>password then
response.write &quo
