Calculate custom field value



We have a project to track progress of various events, including attendee numbers. Does anyone know of a way to use these custom field values and automatically update the custom field in a “Total number” task at the bottom of the project? I.e. 5 tasks with the custom field “attendee #” and then a 6th task at the bottom with the total number. Would love to have this number automatically updated after changing one of the tasks above.

Create totals for numerical custom fields

That’s not exaclty what you want, but if you multiselect the 5 tasks, then Asana automatically sums the custom fields on the window that opens on the right.


Not possible yet, the sum is the only available computation and only if you multi select. I did develop something called Mathana a few years back but it never made it to production :sweat_smile:
