You could probably do this with a temporary counter, such as l_tmpa_int, but the code below defines a new counter l_counter_sum_int and then the sumcounters macro uses seq_map_inline:Nn to add the current values of the counters in g_my_counters, after which it prints the result. The output is the expected:

@noibe Yes, it makes a difference: the code above will give an error because the second and subsequent calls ofsumcounterswill try to define a define a counter that already exists. Alternatively, as I suggested, you can instead usel_tmpa_intinsumcounters, in which case you can drop theint_new:Ncommand completely. (I just checked and this works.)

Instead of performing an assignment, you can also calculate the sum fully-expandably. This has the advantage that you can use it in conditionals, such as
ifnumsumcounters=0 ... fi
I also want to remind you of the expl3 convention to use Hungarian notation for variables, i.e. a variable should carry in its name the data type it holds, usually as a suffix.

Instead of performing an assignment, you can also calculate the sum fully-expandably. This has the advantage that you can use it in conditionals, such as
ifnumsumcounters=0 ... fi
I also want to remind you of the expl3 convention to use Hungarian notation for variables, i.e. a variable should carry in its name the data type it holds, usually as a suffix.
