How can I create a formula to flag booking conflicts?

Hi there!

I'm looking to create a formula that will help me flag conflicts, but I'm unsure where to start.

I have a master project sheet that lists the project name, start date, end date, and company resources assigned to that project.

I'm looking to create a formula that would spit back an error (or custom message) whenever I have a resource booked on two projects with overlapping dates.

Any thoughts on where to start - and which formula to use?

Thanks.
