I have 392 rows of accumulated hours to calculate. I have tried using the
sum function but it only gives 0. However, when I add individual cells I get
a total but it is not correct.
Example:
A1 = 37:10:46.54 and A2 = 23:11:00.00
Formated: [h]:mm:ss.00
Formula: =A1+A2.
I tried using a different time format [h]:mm:ss but I still get 0.

Is there a limit on rows to calculate?
