I am trying to create a tracking sheet for comments in which I want have a column "days open" which shows how many days ago the comment was received from the "comment received" column but that stops counting once I put a date in the "Response Input". I am currently tracking this using the =IF(ISBlank(G2), TODAY() - F2, G2-F2) function and this works but I need to know how many workdays an item has been open. Is there a way to calculate this with workdays instead of all days?
