How to use SUM or other functions to sum the cells of the established IF function in Excel?

Hi @尉寧 羅

According to your descruptions, can you share us with a simple sample to show more details?

Is the data in O2, P2 and Q2 changed dynamically, you want to capture the results shown in one cell that generated via the formula and add these results together?
If so, I am afraid you need the VBA code to capture the result each time and do cumulative calculations.
(But please note, I'm mainly responsible for general issues of Excel client, for VBA code issues, you need to add tag "office-vba-dev". It's recommended to wait for VBA experts' suggestions. Thanks for your understandings.)

Or does the formula will be dragged down for a range? such as =IF(O3+P3+Q3<=80,"80",IF(O3+P3+Q3<=110,"150",IF(O3+P3+Q3<=140 ,"190",IF(O3+P3+Q3<=140,"190","230")))) and so on,
If so, you can use SUM function, and apply the formula to the corresponding cell range of results.
