Hi
I would require assistance in summing up numbers based on the time slots for a day/week. I have grouped the time into 15 mins interval and I cant figure how to sum based on the allotted time slots. This has some 95 time slots and 7 days

Based on the table below....
Based on time in col A, I have to add the daily numbers in col M,T etc. I have sum it in col M, T etc based on the time slots

I have clubbed two time slots together in col Time. I have to manually check the col A and update the corresponding numbers in col M,T etc
Any assistance ?

isn't the output sheet exactly the same as the input sheet - just the row labels say 00:00-00:15 instead of just 00:00
Not sure from your example what you are clubbing together

except you seem to go from 1:15 to 2 in the example
are you trying to do 30 min interval sums , instead of 15min intervals, looking at the highlighted cells

using XL2BB would help (see link in signature or on the menu) - to post an example of the spreadsheet and results wanted or added to a share like onedrive or dropboxs
