The cells in column K and the lines from 66 to 77 contain a formula that sums up all the values in column K.
This causes problems, as another cell (like K77) tries to calculate a value that contains the above-mentioned formula.
In order to get the desired result I need to specify ranges (e.g., K1:K60) instead of the entire K column in cells 66 to 77.
What misled me is that this function returns the correct result in Excel, but not in Onlyoffice.
I don’t know if you could evolve the function in Onlyoffice so that it works like in Excel?
