Clock In/Out - Macro to Log Time by a Switch on multiple columns (multiple rows)

Hello can anyone please help?

I would like to set up in booking in / out sheet for a youth club. The idea is that a person can be clocked in and out using 1 button and that the button will sequentially move along the columns.

I would like this to be allocated to numerous rows where the time can be logged for each individual.

I have attached a workbook, if anyone can help i would be really appreciative. Many thanks.

(Is there a way to make the macro button conditional format Green for in and red for out?)

Thank you for anyone who can help.
