Please read the requirements for the assignment in the file uploaded. I have created a start and stop timer button for each individual. I would like to have one single button to initiate the timer and to stop it. Also, I would like to have the end time of each task for each individual, and a column of the total number of hours worked by department and by task that would be calculated automatically by the code. I have added a list of few names, and I want the code to run automatically if more names are added. If there is any questions, contact me. Thank you.
