Could you also help with a formula for counting checked yes/no
fields. Also, what does the "+1" mean in the formula you wrote below.
Many thanks
"No" is actually stored in a Yes/No field as a zero whereas "Yes" is stored as
negative one. So "magically" if you add one to all of the values the zeros
become positive one and the negative ones become zero. Thus, summing that
expression gives you the number of "Yes" values.
To count the "No" values use...
=Sum(Abs([YesNoField]))
The Abs() function returns the absolute value so negatives become positive and
zero is left alone.
