Cross Check Names And Associated Values To Give A Total

which formula achieves the following:

i have a simple table design with the dates running across the row, below each row i write the name of the person on shift. in the 3rd row i mark the time they are late for work (if any).

below that in a seperate table i have a list of my staff next to that i would like there to be a running total of their lateness. I need a formular that will look for their names and then total any lateness that i have inserted. I have include a basic spreedsheet of what i want to achieve, the column in RED is where i wan the totals.
