Hi @DeanJ, did the response provided by @Melissa help you solve your query? If not, how far did you get and what kind of help you need further? If yes, kindly mark as solution the answer that solved your query. Thanks!
Thanks @Melissa ! This is very close to what I need. There is one other condition though- it could be that no individual sites are selected. I would still need the sum of average per site. With those formulas, I think it is just the average.
One other requirement is that I need the Total to display.
