asp 代码 有错误吗？

<%dim user_name,user_email
user_name=trim(request("u_name"))
user_email=trim(request("u_email"))
response.Write(user_name)
response.Write(user_imail)

if user_name="" then
response.Write("用户名不能为空")
response.End()
'set rs=nothing
'response.Redirect("index.asp")
end if
if user_email="" then
response.Write("email不能为空")
response.End()
'set rs=nothing
response.Redirect("index.asp")
end if
if user_email.value.indexof("@")<0 or user_email.value.indexof(".")<0 then
response.Write("邮箱格式不正确")
response.End()
' response.Redirect("index.asp")
end if
rs.addnew
rs("name")=user_name
rs("email")=user_email
rs.update
response.Redirect("index.asp")
end if
