求教,如何复制完文件后自动关机?

这个我写的VBS,但是改说明后出错了.
on error resume next
　　dim WSHshellA
　　set WSHshellA = wscript.createobject("wscript.shell")
　　WSHshellA.run "cmd.exe /c shutdown -S -t 60 ""文件复制完成，电脑将在一分钟关机，如果不要关机请输入1006···"" ",0 ,true
　　dim a
　　do while(a <> "1006")
　　a = inputbox ("如果不要关机请输入1006 ""1006""　","电脑将在一分钟关机","",8000,7000)
　　msgbox chr(13) + chr(13) + chr(13) + a,0,"MsgBox"
　　loop
　　msgbox chr(13) + chr(13) + chr(13) + "放弃系统关机"
　　dim WSHshell
　　set WSHshell = wscript.createobject("wscript.shell")
　　WSHshell.run "cmd.exe /c shutdown -a",0 ,true
