$dirname ??????

Hi, okay, the following command was given to me in a script, but it's not working and there's little to no help on dirname. What is wrong with the following line? I'm just trying to save the current directory to use later in subsequent scripts.
MYAPPDIR=$(dirname $(dirname $0))

Thanks.
