OK, so I want the output on a differet tab from the data. The Data is on 'All GK Data' (small ' added). The actual range will grow over time but for now lets say I2:I44444. The tab the data goes on is 'HYCO AL'. The cell the data should go to is L20. Maybe now is a good time to add that I want to limit the data to cases where the value in B is equal to cell B1 on the HYCO AL tab and the value in D should be greater than B2 and less than B2 on the 'HYCO AL' tab, Actually I have a similar function working but it is a single value - but very similar in concept. =SUMIFS('All GK Data'!F:F,'All GK Data'!D:D,"=" & L16,'All GK Data'!B:B,"="&'HYCO AL'!$B$1) Since this is sumifs, it is a single value.
