I am working on a work schedule for a group of employees. They are schedule
to work through a range of time. For example, Mr. B works from 8 am to 5
PM, Mrs. C works from 10 am through 5 pm...ect. The layout would be similar
to the one below
A B C D F
Name start end Hour # of workers
Mr B 8 am 5 pm 6 am ?
Mrs C 10 am 5 pm 7 am ?
8 am ?

I want to know the number of workers scheduled for 6 am or from 6 am to 7
am, or each hour according to the range of start and end times to work on
the left side. How to I write a function that would accomplish this on
column F? I know I must use the count function, but I can' t put the logics
into the function. Can anybody help?
