Access radio buttons

Stand alone copy of Access 2003, simply used for tracking sales progress on a single machine.

No tied-in DB’s or modules, just a cust list with a few fields.

It has been so long since I worked with MS db software that I am completely lost again. I wanted to add a few radio buttons so that my rep can just check off a few existing products the client uses and then another set of the same radio buttons so that the rep can check off potential products.

When checked, the radio buttons stay checked for all records, not just the record being worked on.

What is wrong? Any ideas?
