EV3 - Servo port as a parameter

[oracid]

Does somebody can tell me how I can pass a servo port as a parameter ? As I show here. Thank you.

Ok, I find the answer here : https://bricks.stackexchange.com/questions/4309/pass-sensor-or-motor-port-number-as-a-parameter

So, the parameter must be numerical and be 1-2-3-4 instead of A-B-C-D.

It work's.
