为什么我的关机脚本不起作用？

Question

Im running it on Windows 8.1 if I run the shutdown command without the script, it works. But when I run it from this script there is some wrong syntax shown in the cmd.... thanks for help

@echo off
TITLE shutdown timer

SET /P minutes=Enter minutes till shutdown or "no" to stop running shutdowns: 

IF "%minutes%" == "no" (
    shutdown /a
    echo shutdown aborted
) ELSE (
    SET /A seconds = %minutes% * 60
    shutdown /s /f /t %seconds%
)
pause

Answer 1

@echo off &setlocal enabledelayedexpansion
TITLE shutdown timer

SET /P "minutes=Enter minutes till shutdown or "no" to stop running shutdowns: "

IF "%minutes%" == "no" (
    shutdown /a
    echo shutdown aborted
) ELSE (
    SET /A seconds = minutes * 60
    shutdown /s /f /t !seconds!
)

Answer 2

Move the seconds out of the condition and it works:

@echo off
TITLE shutdown timer

SET /P minutes=Enter minutes till shutdown or "no" to stop running shutdowns:
SET /A seconds = %minutes% * 60

IF "%minutes%" == "no" (
shutdown /a
echo shutdown aborted
) ELSE (
shutdown /s /f /t %seconds%
)
pause
