This is my Custom Function and I want to edit it


Here, let me shorten that for you:

m = monthNumber
Case(m = 9 ; "Sept" ; Left(MonthName(Date(m ; 1 ; 2000)) ; 3))

Yeah, I know how to take the left three and account for September. That would be an improvement on this one:

The point of this is NOT to add a "t" to "Sep". It's to use the list for any month name customization you want. IE 1 = Jan, Jan., 1/, 1-, Jy, Jy., First, 1st, 1st., Winter (for a seasonal display calc), etc...

Some developers require customizations for ALL values. An easy case statement like this is a good way to put that together.

But yes, if you just want to add a "t" on "Sep", your calculation is more efficient.
