Question: What would the Excel formula need to be to create an array using this data? I need to make an array that produces the difference
What would the Excel formula need to be to create an array using this data? I need to make an array that produces the "difference" value that corresponds to the same month and tmc. So, whenever column F is equal to column B and whenever the months in row 2 is equal to the "mnth" column in column C, I need an array that corresponds that difference value.
