I am trying to create a sheet that will sum all of the pieces of art that I need for a particular month and year from multiple sheets to get to a portfolio view by month. The formula I put in doesn't identify the month by year. That is my first issue. My second issue is that sometimes I have blank cells or cells that say N/A because the criteria doesn't apply to that particular artwork wave. When I have a blank, it returns #invaliddata. How do I change my formula to ignore these blank cells?
To break down this formula, the first chunk of this formula is pointing to a range of data with the dates of when artwork will be complete, the second chunk of this formula is the criteria which is month which is in one of the columns on my spreadsheet, the third chunk is pointing to a range of data with the number of POAs in a project.
SUMIF({High Level Artwork Status: FK DATE}, MONTH(@cell) = [Primary Column]@row, {High Level Artwork Status: POA Count})
