China DOS Union

I've just started learning batch files.
Why does this simple script jump to First every time?
Friends who understand it, please help explain it, thanks.
Also, could you introduce how choice return values work?

@echo off

:start

choice /C:FSTO /M "First,Second,Third,Out" 

if errorlevel 1 goto First 

if errorlevel 2 goto Second 

if errorlevel 3 goto Third

if errorlevel 4 goto end

:First

echo This is the first line.

goto start

:Second

echo This is the Second line.

goto start

:Third

echo This is the Third line.

goto start

:end

echo bye!

ErrorLevel x means a case greater than or equal to x! So you have to write it in reverse order!

if errorlevel 4 goto end
if errorlevel 3 goto Third
if errorlevel 2 goto Second
if errorlevel 1 goto First

This is the mistake beginners are most likely to make when writing ErrorLevel ^_^

Check the help yourself for how to use chioce!

RE ziver :
A: Using this forum's search function instead of asking for help will save you a lot of waiting time, and you'll also be able to see more examples and understand more.
B: Error codes should be tested starting from the highest value and going downward.

if errorlevel 4 goto end
if errorlevel 3 goto Third
if errorlevel 2 goto Second
if errorlevel 1 goto First

C: If you don't use error codes for testing, you can test based on the character input by the user. See link {1}
