Okay, I put in the following formula:
=XDATE(YEAR(B14())-A17,MONTH(B14())-B17,DAY(B14()-C17))
where B14 contains 10/7/1849 and A17 through C17 contain 61, 11, 22. I am getting a #VALUE! result.
Any suggestions? I didn see any other XDATE functions that would be of any help but this looks like it should work. I think it's just me being dense.....
