how to sum the concatenated value

use calculate(average...) in a VAR and so on

Could you help me to implement this suggestion? I have a table with some activities and related durations in seconds. I need to calculate the avg of durations and display the value formatted hh_mm:ss in a card. If

@EnricaTunesi70, You need to sum the values BEFORE you run it through this measure because the original formula is only used to display the final result as text for visual purposes, not to do calculations.

I have a line chart where I'm trying to show the minutes:seconds in the Y-axis.

When I apply the Duration fields that I created, it only allows me to have a count, which is always 1.

Any ideas?
