I'm trying to create a calendar vacation spreadsheet but I want to avoid
having certain department managers/supervisors from taking the same days off.
Is there a way to create a spreadsheet that will help me do that? For
instance, if I enter a date, and a manager already has that scheduled off, is
there a formula that I can create that will give me a pop up message that
says "date already taken" or something similar to that? Thanks in advance
for any help.
