I have a calculation to calculate the number of days between two columns.
=IFERROR(NETWORKDAYS([Date Submitted]41, [Go Live Date]41), " ") It works great to return a blank if the customer has not gone live.
Then I have formula to calculate the average of the cells.
=AVG([Number of Days to Implement]12:[Number of Days to Implement]41) Also works great !
I now want to calculate the average based upon a region (EAST, WEST, CENTRAL, MOUNTAIN)
I tried this formula but it is not working.
=AVG([Number of Days to Implement]12:[Number of Days to Implement]41, [US Region]:[US Region], "Central")
Any suggestions?
