Each session can score the following behaviors: Observe, Engage, Assist and Promote.
The end of the form for that session is to display the scores for each behavior. Since the participant is graded several times on Assist and Promote, each of those should be averaged prior to display.
I can get each of the individuals to display. However, I need to take all of those values, add them up and then average the result. I keep getting an Invalid Expression error (see screenshot) for the Total Score (expression is shown below). Any ideas on what to do and how to fix this?
