Thank you for your post.
Without knowing how your tables are set up, Player 1 will either have a higher score than Player 2, or a lower score. In either words, and either/or situation. Therefore, a calculation field resulting in type Number could be:
If ( Score > Opponent Score ; 1 ; 0 )
If you then create a Summary field that averages the calculation field, you will get a win percentage. That is, if Player 1 wins 3 times and loses 1, the average of 1, 1, 1, and 0 is .75 or 75%. Does that make sense?
yes...this made perfect sense and worked on my first attempt....thank you!
