Im having a problem in google sheets. I want to sum 2 columns the time that a driver is driving without the stops. So im using this formula to do it:
G7 is 10:20 value and H6 is 10:00.
But I want to do it in all the lines, but when I use the same formula:
I get this value:
Any idea how can I ignore the zero values that are making my database giving me wrong values when in this example the result I want is 00:40. The time driving without the unloads?
