Hi Lamar!
When you put a check box in a frame control then it is given a frame value: 1, 2, 3 etc. Then the frame control's value is based on which check box is checked. You can bind the frame to the field and Access will store the value based on which box is checked. The values are given to the check boxes automatically when they are placed in the frame but you can change them to whatever values you like.
I should make one change, I think you need to use radio buttons instead of check boxes, but I am not sure, the check boxes may work that same way as the radio buttons.
