Good morning as per the attached code, I would like to create a function that if the work shift (dienstdauer) is more than 10 hours, a 25% surcharge is created for every minute worked after ten hours.
I should have a result in minutes so that I can then add it up and convert it to excel.

Also in the nachtzeit column the 10% surcharge is calculated for every minute worked between 10 am and 6 am, as you see in the table it is transcribed in hours and minutes, I should have the result in minutes again so that I can add it up and convert to excel.
The function was created with the help of user @constantstranger whom I thank again!

Thanks
