I have an evaluation form that I created that has 14 different evaluation areas in it(Planning, Budgeting, etc). Within each of these 14 areas there are various "traits" that a person is rated of from one to 10. As I rate each trait I get an average for the entire area being evaluated. That evaluation total is then populated in an "Overall Evaluation" summary section which captures the final average for each evaluation area. I then have a final score area which sums up all of the 14 averages and divides them by 14. The problem is, is there is one evaluation area in which an individual is not rated, this total will be "0" and I need to exclude that "0" from the final score (which normally would divide all scores by 14). This in turn, throws the average off.
Any help would be appreciated.
