I'm attempting to get a running count of unique dates based on user (to categorize how experienced the user was for that row) however I can't seem to figure it out. I've tried a variety of countifs and countuniqueifs but keep getting an error - I would like to it to count unique dates less than or equal to the date listed in that row, if that makes any sense. Words are hard. Here's a link. Can anyone help? any assistance will be greatly appreciated.https://docs.google.com/spreadsheets/d/1aPM9YAo8qstmYov3-5v6DOG145z1qaURgIxMuPWVitw/edit?usp=sharing
