There is nothing like this in the file you attached, and there is only one sheet.
Using a 3D reference with a range of sheets is based on the order of the sheet tabs. Based on your description I would create a dummy sheet that is always the rightmost tab, and one in the leftmost tab, then in insert new sheets between the dummies. Then your 3D formula should work with no further changes.
