and I also can separate the forumla in 2 cells by putting in the last ELSE
clause to look in another cell that contains more ifs

Thanks for the hint! it helps

You are limited to 7 levels of nested functions. Perhaps you can use
VLOOKUP or CHOOSE instead of a series of IFs.

Hello!

How many tests functions does Excel authorizes in one formula?
for instance:

=IF(...;...; IF(...;...IF(...,... IF(...;...; .... ))))

I went up to 8, then I get an error message asking me to check the
parentheses the punctuation.. even if it's correct.

Thanks for any suggestion!
