The sheet above shows Machine run time and loss time and I have assigned a loss grade for each incase there is any. (A, B, C, D, E, F).
This Sheet shows the total loss for each machine.
I want to calculate all the loss time for each grade and machine. For instance, if loss grade is A, only the loss time should be calculated with a A loss grade. Let me know if you need more information. Thanks for the help :)
You can do it with Sumifs:
=SUMIFS(Sheet1!$F5:$AA5,Sheet1!$F$3:$AA$3,"Loss Mins",Sheet1!$G5:$AB5,D$1)
for first three rows.
