I need Help... anybody

[Birnen]

Good morning.

I come once again ask you to help / makes clear.

Attached is a table of example, in order to understand what they are asking me to do here at work.

I know how the cell itself, but what they mean is that the result appears in the middle column or the cell itself, is seen in the cell Columa A or B, but via a macro. Ie the end of the table is complete, click on a button with the macro, and that this macro will change the value of A greater than B and the same for column B is greater than A. And not doing anything where values are equal.

And if possible without this macro conflict with a formula that is already in the cell?

--- I have make some chancing on the example.
