This is my Custom Function and I want to edit it

I had trouble wrapping my brain around this and had to try this in a test database to see how it actually worked.

A supplied date of 12/15/2000 would evaluate to "13/0/2000", and FileMaker does the math, properly returning "12/31/2000".

Nice, simple function!
