Help With general coding please

Robin2:
Who? From whom?

Post a link to the Thread where you got the code.
Why did you not ask your question in the Thread where you got the code?
Why not ask the person who gave you the code to help out?

More generally, why not describe what you want to achieve - maybe there is a much simpler way.

...R

The much simple way was to call these and based on there order it could start the next timer

  }
        else if (mode == 'N') {
            for (auto& t : timer) {
      timer[2].stop();
      timer[1].stop();
      
      
  }
   Serial.print("T 1 Started");
    }

    else if (mode == 'O') {
            for (auto& t : timer) {
      timer[0].stop();
      timer[1].stop();
      timer[0].stop();
      
  }
  Serial.print("T 2 Started");
    }

       else if (mode == 'P') {
            for (auto& t : timer) {
      timer[0].stop();
      timer[0].stop();
      timer[2].stop();
      
  }
  Serial.print("T 3 Started");
    }

duct tape.
