I am trying to create an analytics table for my reatail business and I created a sheet that includes all the poducts. I have a different table per day that I have sells so in the analytics table I added a column and linked the sells I have per day.
What I want to do is to rollup all colums I have in the analytics so I can see my sales per day. How can I rollup sum different colums to get a total per month???
