Formula to work out how many products among various products!

Hi all,

Im new on this forum so I apologise if I dont explain my dilemma too well.

I have an assignment and one of the criteria is this..

Enter Formulae in cells H2:H5 that work out how many books, Dvd's, CD's and Computer games are in the spreadsheet.

Another criteria is

Repeat the above but work out the Total price of all the books, Dvd's, CD's and Computer games

I havent used spreadsheets for a while and im completely stuck.

Please help

If you can explain it as simply as possible I would be very grateful

Thanks
