I already have info and when I custon and change to YY/MM it changes all the years to 19 from any year age ie 10/11 = 10yrs 11 monthes. but when I custom format the cell it changes to 19/11 - any ideas. I wasting to much time that I don't have on trying to work this out my self - fingers crossed and thank you for reading my thread
