如果只删除一个，是好的。但是如果点前面的选框来多个同时删除的话，就会报错。但是报错后还是会删除选取的最上面的那一个。

在读取到这一块的时候（第48行）
if request("Action")="Del" then
            delarr=Split(request("FileName"),",")
                For i = LBound(delarr) To UBound(delarr)
                whichfile=server.mappath(delarr(i))
                Set thisfile = fso.GetFile(whichfile)
                thisfile.Delete True
                next
                response.redirect "Admin_Upload.asp"
        end if

会报错，显示的是
Microsoft VBScript 运行时错误 '800a0035'

文件未找到

\wwwroot\ryzs\admin\Admin_Upload.asp, line 48

求高手帮解决一下。
