Need access database for inventory

I need to create access database for my company for managing my inventories in my stockroom.
I need it to have 5 categories and in each one of them I want it to have a couple of items.
I tried with a template, but when I entered different items in each category it showed me the total amount of items in the entire category, but i want it to show me the count of each item separately.
Any ideas how to achieve this?
