This is the way I would do it:

You have 7 shows.

__ __ __ __ __ __ __

The first slot there are 7 options available.
7 __ __ __ __ __ __

The second slot there are now 6 available
7 6 __ __ __ __ __

Continue that pattern.

And I know that to solve this you multiply each slot 
So 
7*6*__*__*__*__*__
