With Start Times in Sheet1 A2:M2, End Times in Sheet1 A3:M3 and with times
in Sheet2 A2:A50 try:

=SUMPRODUCT((Sheet1!$A$2:$M$2<=A2)*(Sheet1!$A$3:$M $3=A2))

But if your wife works in a 24 hour supermarket then you will have trouble
with midnight so I suggest that you enter midnight times as 0:01 and 23:59

My wife has asked me to create a sheet that will give her the following
info.

She works in a store with a number of checkouts. The sheet will have all
her staff start times and finish times. This will be inputted every day.
Excel will then create another sheet that will show the time of the day at
30 min intervals how many checkout staff is on at that time. Nothing too
fancy, I have been sitting here for two hours trying to figure this one
out. I have a screenshot of the info if anyone wants it if I'm not clear
enough.
