This is my Custom Function and I want to edit it


In my experience this function only works if you replace all StartDate references with getasdate(StartDate), and replace all occurrences of EndDate with getasdate(EndDate)

(Both Mac/PC and FM9-11)

This custom function does not work (at least for me), it would be great if someone could revamp it for version 16.

I added this to the calc:

Let (
StartDate = GetAsDate ( StartDate ) ;
EndDate = GetAsDate ( EndDate )
] ;
original cf formula here...

and it worked in FM16
