batch choice command will not work

I have this question about why this choice command won't work. I've looked on this site and compared all my scripting and I just can't figure out why it won't work http://www.computerhope.com/issues/ch001674.htm

@ECHO OFF
:START
echo 1 to quit or 2 to print hello and go back to this screen
CHOICE /C:12 /N
IF ERRORLEVEL ==1 GOTO QUIT
IF ERRORLEVEL ==2 GOTO HELLO
GOTO :START
:QUIT
EXIT
:HELLO 
ECHO hello
GOTO :END
:END

I've made a couple of changes and removed unnecessary code.

@ECHO OFF

:START
CLS
ECHO=1 to quit or 2 to print hello and go back to this screen
CHOICE /C 12 /N
IF ERRORLEVEL 2 (CALL :HELLO & GOTO START)
EXIT /B

:HELLO 
ECHO=hello
TIMEOUT 2 1>NUL
