That command works fine for me:

$ MAGIC_OFFSET=42
$ file=/etc/motd
$ MAGIC_NUMBER=`od -An -t u4 -N 4 -j $MAGIC_OFFSET "$file" | tr -d ' '`
$ echo $MAGIC_NUMBER

What's the exact error message that you get, and what are
the values of the variables involved?

By the way, when debugging shell scripts it is very helpful
to run the shell with -vx.  Then it prints the script as it
is being parsed, and additionally each command is printed
after expansion.

Best regards
