Hello, Ive used countif and sumif statments alot but not utilizng multiple sheets usually the data and formula are all on the same sheet but i Have a worbook that has a years worth of data on it and each month has its own tab. I am creating a summary page at the front and I know i can just manually go through and look for the specific data on each sheet and do a regular addition formula but that could take along time. What I have is Markets as column A and then for instance two columns for member non-member. I want the summary sheet to tally the markets for these different items. For instance if my market is Downtown I want ot know over the course of the year how many items there were sold downtown and if they were sold to members or non members.
