I am using a VLOOKUP in a set of merged cells (C22:K23) to create a brief description. The description changes each time one of 12 cells (E8:E19) are selected. The description goes away when a cell outside of these 12 cells is selected. I am currently doing this with the Calculate function in the SelectionChange Event. However, now a user can't do anything else on the sheet because of Calculation running every time a new cell is selected.
How can I only Calculate the cell containing the VLOOKUP function?
