Count records until a record value changes

BobThornton · Nov 15, 2022

Thanks in advance for all of your help, it is greatly appreciated!

I want to count the number of 'N' ANSWER records until the value of ANSWER changes the first time.
So in below the count would equal 3
How can I do this?
Please see below

ID ANSWER DATE RANKING
12345 N 11/7/2022 1
12345 N 10/7/2022 2
12345 N 9/9/2022 3
