I am making a relational database using access for a newsagent for my A Level cursework. The owner has several customers who require a newspaper on different day. So on my table i have made a tick box (Yes/No, Data Type) for days Monday - Sunday. In another table i have the newspaper name with the prices. I want to be able to add up all the ticks for one customer so that i can multiply it byt the cost of paper that they order. Please can someone help me.
