I am trying to find the avg of a value base on a range of dates. In column A i have the dates (there are empty cells in this column", column C I have the value i want to AVG. i am using the following formula =AVERAGEIFS(C:C, A:A, "<= 1/1/27", A:A, ">= 1/1/2021"), but continued to get a #/div/0. There a plenty of line items with date in between the criteria, I am not sure if the blank cells are causing the issue or not. I have also try doing the following =AVERAGEIFS(C:C, A:A, ">= 1/1/21", A:A, "<= 1/1/2027") and i get the same error. can you help me? thanks
