Hi All,
This should be simple....
To make my question clear, I put a demo table here:
http://tallahasseech.org/accessquestion.htm

- I want to assign the number '2' to each yes and assign '1' to a "no"

- I want to then add up all the numbers in the fields for each record (person)

> So the answers for my demo would be:
tom = 7 (2+2+2+1)
tim = 6 (1+2+2+1)
james = 0

How do I do this.
I appreciate the help.
Paul
