Please, I need help to activate the formula in the flat
If you have an English version, you need this:
= IF (B5-A5 = C5-B5, (B5-A5) -1, ")
If it's a Portuguese version, you need this:
= SE (B5-A5 = C5-B5; (B5-A5) -1;
Sorry I cant help you. As ususal you have not properly explained what you want to do.
The spreadsheet does not help, it conveys no useful information.
You have not explained the formula , it has nothing to do with difference of 2. Whatever it is doing it works, but what is it working on ?
Write your answer down on a sheet of paper, read it, ask if someone else might understand it, if not think again. Do not post until you have cleared your mind of irrelevant clutter.
ONE SINGLE CLEAR POST ONLY !!!!!! NO "WAR AND PEACE", No "LORD OF THE RINGS", just a short CLEAR explanation.
