Please help me with scan in and scan out sheet

I'm trying to set up an excel sheet to record different task for multiple employee to keep their time in and out and able to calculate total time spend on the jobs. This is what i have up to now. I'm not sure how to code for the time in and time out and total time per job
'm trying to set up so a person(Manager or production supervisor) can assign the task by scan in employee ID (could be multiple) and jobs (could be multiple or single) that assign, that would let me record time in ...Then when employee finished with that jobs, the person (manager or prod s) scan out for that job. So i can capture the total time assigned for that jobs.
