I am formatting my cells and in Equal to Zero and Undefined sections I am putting - (Hyphen)
BO does not take - in the Equal to Zero section where as it works fine in Undefined section.
If I write some other alphbet in Equal to Zero part it works fine.
It does seem to like only the -
How can I show that - (hyphen) in the cells having zeros.
Well, I just tried it, and I can confirm your findings. It allows anything other than a dash. I tried wrapping it in quotes (double and single), and it still wouldn’t work.
