    I need to know how many combinations there are if I need to select 1 item from each category ...

    I'm probably late but here is my solution -

    You need to be more specifics - Do you mean how many combinations if I pick only one item for each category and they are 4 category with 4 item each? That's 256 different combination

    But if you mean how many combinations is possible if I have to at least pick one item for each category and they are 4 category with 4 item each? That's a little more complex but the first part of tribe link will help you out- I think the answers is 50625 - Each group has 15 combinations and you have 4 group - so 15^4 = 50625.
