move files using wildcard

I have the following requirement.

PATHA =/opr/itr/
PATHB=/etc/data/
FILENAME=*abc*

file name is wild carded as there could be many files with name abc anywhere

I tried mv $PATHA/$FILENAME $PATHB
and I got a error that /etc/data/ can not be created

Could any one please help.

Thanks

This really does sound like a homework problem...
