PLEASE help me!!!

after i've entered all the codes:

root
mkdir /home/opt/rovio/angrybirds/data/levels/pack2
cp /home/user/MyDocs/mypack/* -R /home/opt/rovio/angrybirds/data/levels/pack2

i got this "cp: cannot stat ' mypack/* ': No such file or directory"

but i've already pasted the mypack folder into my local storage..

thanks..
