Formula autofill help
Hello, I m learning excel and for work I need to combined large chunks of data from one sheet to another. I came up with the formula =SUM( 940748 SB Class 05-08-23 !F1:F12) in the second sheet for the first batch of data from sheet one. The problem I am having is when fill down the formula I need the cell range to increase by increments of 12 not 1, so F1:F12 becomes F13,F24 when I fill down one row. My knowledge of excel is very limited so I have no clue on were to even begin to get this done.
