Lets say the green timer is set to 02:00 and when I hit "start" it starts to count down. When the green timer has reach 00:00 I want the red timer to start count upwards from 00:00 till I hit the stop button. and lets say I stop the red timer at 01:15 then I want excel to store that data in another sheet.

And now I can only get the green timer to work. I cant figure out the logic between the two timers and how to store the data when hitting the stop button.

I will give you some context.

The green timer will show how much time you have to do a task if you've not managed to complete the task in time I want the red timer to count how much time you have gone over. And then store this in a sheet so I can follow up the total "overtime" when all tasks are completed.
