当我输入内容时，批量程序出现意外

Question

好的，所以我制作了一个批处理游戏，现在我正在通过教程编写代码。我的计划是使滚％％

set /a roll=(%random% %% 7) + 1 

能够带走%enhealth%和%yourhealth%

:foresttutorial 
cls 
echo. 
echo __________________________ 
echo |       | 
echo | An enemy appeared!  | 
echo | Enemy health: %enhealth% | 
echo | Your health: %yourhealth%| 
echo |       | 
echo | 1. ATK 2. USE POT  | 
echo | 3. GOLD 4. PASS  | 
echo | _________________________| 
echo. 
echo Here appears an attack screen! 
echo Quick, press 1 and enter! 
set /p choice8 
if %choice8% == 1 goto atkforesttutorial1 else goto invalidforesttutorial1 

:invalidforesttutorial1 
cls 
echo Invalid answer. You can try the other options soon, 
echo for now just press 1. 
pause 
goto foresttutorial 

:atkforesttutorial1 
set /a roll=(%random% %% 7) + 1 
set enhealth = %enhealth% - %roll% 
echo You attacked the enemy! 
echo. 
echo __________________________ 
echo |       | 
echo | An enemy appeared!  | 
echo | Enemy health: %enhealth% | 
echo | Your health: %yourhealth%| 
echo |       | 
echo | 1. ATK 2. USE POT  | 
echo | 3. GOLD 4. PASS  | 
echo | _________________________| 
echo. 
pause 

以上是我的代码。当我为FIRST框输入1，然后单击enter时，它会弹出一个闪烁的“1意外...”或类似的内容。有想法该怎么解决这个吗？ 全部代码在这里： https://pastebin.com/kBNgNV1G
