I have a table that uses data from two separate tables in its formulas.
However, because the calculated table does not correspond row by row to the
source tables, the fill down of the formulas in rows of 3 for Week 2 (rows
17,18,19) and the next 50 weeks will not work properly. I want to fill down
rather than type the formulas in for each week. I tried making the row or
column static, but that still lets the row or column that changes change by
three and not by 1. I looked into OFFSET, but I can't figure out how that
would work. Can anyone help me?
