Adding times

[AlanM]

Hi, I'm new to this forum. I want to add two times together on Planmaker, e.g. 4 minutes and 20 seconds +1 minute and 23 seconds. I am using the format 4:20 and 1:23, but can't see how to do the addition. Can someone please tell me. I've got hundreds of these additions to do and would prefer to do it on Planmaker than use an online calculator as I want to keep record of the input data and results.

Hi,

I checked it works, when you set the format of the summary cell to "Time".
