numbers,sumif,non-contiguous,range
I am trying to sum positive non-zero non-contiguous ranges of cells on the web app for numbers on icloud.com. I have so far been unsuccessful in doing this because when I do it with a sum() function it will return the number of hours in decimals of an hour, instead of returning it as x hours y minutes. The web version doesn't have a way to format the cell as duration. even if i set it as duration it doesn't want to return as i want it displayed as x hours y mins. the only way it will do this is if the cells I'm summing are positive nonzero values. it seems to be a quirk of numbers because if I sum the same cells in Excel on windows it correctly returns x hours y minutes.
Is there any way to solve this? I'd greatly appreciate any help.
