I have a file I have used successfully for 3 or 4 years. I am using Excel 2016. Now all or a sudden some formulas don't seem to recalc successfully. The suspect formulas are verifying that the sum of a lot of SUMIFS() formulas equals the total of the data that is being extracted selectively in the SUMIFS. The ONLY way I can seem to get them to recalculate is to hit F2 and then enter on those formulas. Quite annoying. Anyone have suggestions?
