I have a table with 2 columns:
Column A is called chapter title, Column B is a time in minutes:seconds
As an example there are 10 Rows in my sheet. Each row has a time value in column B. BUT not each row has a value in Column A. Ex: Chapter one could have 3 times, Chapter 2 could have 4 and Chapter 3 Could have 3.
How could I easily count the number of Chapters AND count the number of times in each chapter.

Thanks in advance
