Set /P not capturing input in IF statement

Everything in this batch script works fine, but when I enter the IF statement, for some reason set /p id= doesn't actually capture anything. In fact shortly after it will echo:

You chose session %id%.

but that will return a blank, as though nothing was entered for ID.

Any advice would be greatly appreciated.

@echo off

echo Please be sure CMD is being run as an administrator.

echo.

:loop

set /p targetpc="Which PC would you like to query for users (Hostname or IP)?: "

echo.

echo Querying %targetpc%...

echo.

quser /server:%targetpc%
echo.

set /p choice="Would you like to log a user off of %targetpc%? [Y/N]: "

echo.

IF /I "%choice%" EQU "Y" (

    echo Enter user's session ID:
    set /p id=
    echo.
    echo You chose session %id%.
    echo.
    logoff %id% /server:%targetpc% /V
    echo.
    echo Done!
    echo.
    goto loop
)

IF  /I "%choice%" EQU "N" (

    goto loop
)
