I have a problem with my Excel sheet.
"Kolom4" has the product codes. Each code has two rows with data. With each code I want to have the combined values of "kolom11" till "kolom14" from both rows.
So for example for product code 10303814140001 I want the values 0 (0+0), 13 (10+3), 0 (0+0) and 13 (10+3)
See:
The problem is there are hidden cells between these values and I don't know how I can make a formula which can calculate them together without the hidden cells and with which I can pull down to do it for the entire data file.
