Hiya,

I have a CSV file, that contains people's Ages, First names, and Surnames. If an age is duplicated more than 7 times, how do I delete the Firstname and Surname from the file for that age?

Example:

15, Danial, Green
22, Neil, Hall
15, Phil, Sheen
17, Micheal, Snowfield
15, Peter, Davis
15, Simon, Scotland
77, Dave, Erin

*The 6th row (Shown in Red) should be deleted.
