大家帮忙看看，我一直找不到问题，纠结啊。。。
<%
    dim Nick,Password
    Nick=Request.Form("Nick")
    Password=Request.Form("Password")
    set conn=Application("conn1")
    set rs=Application("rs1")
    sql="select UserID,Passw from Users where Nick='"&Nick&"'"
    rs.Open sql,conn,0,1
    if rs.BOF and rs.EOF then
        rs.close
        set rs = nothing
        str1="<script>alert('登录名不存在！');history.back();</script>"
        Response.Write str1
    elseif rs("Passw")<>Password then
        rs.close
        set rs = nothing
        str1="<script>alert('密码错误！');history.back();</script>"
        Response.Write str1
    else
        session("Nick")=Nick
        session("UserID")=rs("UserID")
        rs.close
        set rs=nothing
        Response.Redirect "default.htm"
    end if
