顶上去吧..

没有语法错误~！

你把类似 as unum的dd去掉看看

set rs=server.createobject("adodb.recordset")
sql="select (select count(id) from love_main where username='"&username&"') as unum,(select count(id) from love_main where email='"&email&"') as enum,(select count(id) from love_main where tel='"&tel&"') as tnum,(select count(id) from love_main where zjhid ='"&zjhid&"') as znum"
rs.open sql,conn,1,1
if rs(0)>0 then response.Write "<script language='javascript'>alert('用户名已经被注册!');history.go(-1);</script>"
response.End
else if rs(1)>0 then response.Write "<script language='javascript'>alert('邮箱已经被注册!');history.go(-1);</script>"
response.End
else if rs(2)>0 then response.Write "<script language='javascript'>alert('电话已经被注册!');history.go(-1);</script>"
response.End
else if rs(3)>0 then response.Write "<script language='javascript'>alert('这个证件号已经被注册!');history.go(-1);</script>"
response.End
else
rs.close
set rs=nothing
