I have a simple formula I am trying to run in excel. The data I have below is a total time, I am trying to add this data using =SUM(A1:A6) however this returns a value of 0:00:00 when it should add the values together. I have format on the cells of [h]:mm:ss
0:16:09
0:13:22
0:00:00
0:00:00
0:00:00
0:00:00
Total: 0:00:00
Not sure if this is something simple I am missing.
