Hi guys

Hope you all are doing just great, Please I have a slight issue and how to get around this

Am trying to count Column column A and I need my result in Column B based on the criteria
Example of what I need:
in column A I have 1 repeated twice, so I will need column B to count as 2 and when i drag down I need the next to be blank
I need the same result as this on the table

Appreciate your support
