I have a form that will be used to collect info on conferences attended (one repeating box), and lectures attended (a repeating box within the first repeating box).
I have calculated the number of hours per conference and would like to take that calculation and add it up to give a final tally of all conferences attended. I am using the following:
Which is identical to the method used to calculate the individual conference total, but I just can't get it to work for the final total. What am I doing wrong? I get the error about the aggregate method at
character 22 (Sum).
