Adding Months to a Date
The Date formula allows addition but I get errors when I cross months by adding days or when I cross years by adding months. (Haven't tested years with adding days but that also crosses a month so I would get an error anyway.
I need it to act like Excel and actually add a year for each multiple of 12 months in particular. Days is annoying but I can work with that in other ways.
So I created a formula to force this on the frontend.
But it is acting weird. There are times it works, I was testing a Start Date of 11/1/2019 and a duration of 4 months. It worked. Make it 5 months, it says "#Invalid Data Type" - but the column is set as a date type. If I break out the parts, I get a variety of errors but sometimes it works. I even get all three to work and when I put it together, it breaks. So I can get the year to say 2020, the month to 4, and day to 1. But paste all those into a date formula in a date column and it gives me the error. A little frustrated.
I suppose I could use Netdays * 30 but I am stuck on this should be so simple and should work. It is the principle of the matter.
