When a function computes 0, how do I make the cell display 0hr 0min
I have a function in a column of cells, and format to display the calculated value in duration "hr min". So long as the function calculates a positive value, that value is displayed correctly in "hr min". However, when the function calculates a value of 0, that value is displayed simply as "0", instead of "0hr 0min". When I check the format of that cell, it shows automatic, instead of duration.
I have found a workaround by placing that function within the duration function.
