Hi everyone,I am trying to create a spread sheet that adds up my staff's hours worked for a rolling 119 day period, sounds easy but I have to ignore any day that they have taken as leave but still include a 119 day period. For example if I had a member of staff who took 6 days off in that 119 day period I would need to add in the extra 6 days at the end, so I would need a 125 day period to be calculated.Is this possible? At the moment I have the rolling 119 day sum and a countif to tell me how many days leave (input as L) and then I manually add the extra cells to the formula. So my formula reads =SUM(C2:DQ2)+SUM(DR2:DW2) as my employee has taken 6 days leave. Many ThanksStu

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.

Well, where is the leave count? Just add that to the sum

I have the leave count in row 3, so I have a rolling 119 day period of leave as well, but I'm not sure how to automatically adjust the formula to include the extra days. I have 45 members of staff so I'm looking for a way to automatically calculate the rolling number of hours worked rather than having the simple total and having to manually adjust the formula for every leave day.

Dummy example of what I'm trying to achieve -

Staff #Name01-Jul02-Jul03-Jul04-Jul05-Jul
1Jones10100L10

<tbody>

say I need to calculate a 4 day rolling sum of hours Jones would be 20 hours but because he had a leave day I need to do a 5 day rolling sum to account for his leave day. Therefore his total would be 30 hours. I need to expand this to cover 119 day period so not as easy as just looking and amending.

Thank You
