@rorya this works great! I just noticed though it doesn't work for people younger than 9, even though that data is available on the Nutrition Data sheet, and at that age the values ignore ***/gender and also include months. Can that be incorporated somehow? I don't mind changing the way the values are displayed (0-6 mo could be 0-0.5 years).

@JeteMC Thank you for the explanation, I'm not sure I follow the index portion or the "arguments" section of the aggregate function but I definitely have a better grasp of the concept. I'll look into these gaps in knowledge later. Thank you very much!
