A while ago I needed help with a solution to calculate weight variances in Filemaker Pro 12. I have another problem if anyone could help. I need to get current weight, 3 months prior, 6 months prior, and 1 year prior for each patient to show up either through a portal or a report using fields "entry date", "weight", and "percentage variance". Is it possible? i have to keep into account some weight entries may be left blank in wich case the previous one should be used.
