I am having some trouble with using the LOOKUP function on a sheet I have. We want to use a form to create a ad placement name that includes abbreviations of what the user selects. I am finding that the LOOKUP area shifts as new rows are added. I set all my lookup tables at the top of a sheet and then the new rows are added at the bottom. As the formula duplicates, the LOOKUP range shifts down too causing my naming to not work. Is there a way to lock in the LOOKUP range?
