I need to add an IF statement into an INDEX MATCH formula that pulls the system size of a column if it is not blank.
This formula will be on sheet #1 and needs to be an IF, INDEX, MATCH. Sheet #2 will have the actual system size column and Sheet #3 will have the target system size column. The formula should pull from sheet #2 (actual size) but if no value is present, then it should pull from sheet #3. All sheets have a column, Project ID, which is what we will INDEX MATCH with.
Is it possible to put this all in a formula?
