我在另一个页面得到是这样写的.
<!--#include file="conn.asp"-->
<!--#include file="select.asp"-->
<%
ary=Filter(session("ary"),"n")
ary=join(ary,",")
%>
就是空值,什么也得不到
如果给ary=Filter(session("ary"),"n")删除了
改成
<%
ary=join(session("ary"),",")
%>
会报这样的错
[free]Microsoft VBScript 运行时错误 错误 '800a000d'

类型不匹配: 'Join'

有人知道什么原因吗?怎么改吗

join是怎么定义的?
