Hi, I have a file I'm working on for a physiotherapist. It lists all patient appointments and she wants to be able to count how many appointments a particular patient has had. I have been trying to use the COUNTIF formulas to say if First name = X and last name = y to count how many instances they appear (this needs to be done as some have the same first names or surnames).
E.g
Joe Blogs
Fred Mcfarlan
Billy Friday
Billy Friday
Billy Friday
Billy Tuesday
Billy Tuesday
So I want to count how many times Billy Friday has had appointments with me, what formula would I use to get that data?
Any help would be much appreciated!
