Changing % complete using a formula in another cell
I know you cannot use a formula in a "% Complete" field. Is there a way to update "% Complete" from a formula in another column (something like a "helper" column)? I have a "Task Status" column with drop down values of Not Started, In Progress, and Complete. I would like to change the value of "% Complete" when I change the value of "Task Status". (e.g. If [Task Status] = "Complete" then [% Complete] = 1). Is this possible?
