hiding warning symbols
HI everyone,
I made this chart to keep track of my gas mileage and as you can see it tells me that you cannot divide by zero, but when I have numbers in the two boxes it works fine. So please tell me how to get rid of the red triangle and leave the box blank, because I want to average the MPG (H) column.
Thanks for your help,
Mike
