displaying string from Arduino

I control manages speed dc motor , I want to show the speed that is read by arduino , but the speed sent by arduino can only appear on the monitor serial processing , all I want is a display in the window " run" . this is processing code :

          `import controlP5.*;
            import processing.serial.*;
            ControlP5 cP5a;
            ControlP5 cP5b;
            ControlP5 cP5c;
            ControlP5 cP5d;
            ControlP5 cP5e;
            ControlP5 cP5f;
            ControlP5 cP5g;
            ControlP5 cP5h;

            Serial arduino;
            String val;

            void setup() 
            {
              size(785, 520);
              println(Serial.list());
              arduino = new Serial(this, Serial.list()[0], 9600);

              cP5a = new ControlP5(this);
              cP5a.addSlider("ATUR_KECEPATAN_MOTOR_DC", 0, 255, 0, 30, 155, 350, 50);
              cP5b = new ControlP5(this);
              cP5b.addButton("FORWARD",1,30,220,100,40);

               arduino.write("c" + val3);
                }
             if(theEvent.controller().name()=="BUKA_GERBANG") {

               arduino.write("d" + val4 );

             }
             if(theEvent.controller().name()=="SUDUT_SERVO") {
               int val6 = int(theEvent.getController().getValue());
              arduino.write("f" + val6);  
             }
             if(theEvent.controller().name()=="MASTER_ON") {
               int val7 = int(theEvent.getController().getValue());
              arduino.write("g" + val7);
             }
             if(theEvent.controller().name()=="MASTER_OFF") {

               }
              }
            }`

in this section :

    if (arduino.available() >0){
    val=arduino.readStringUntil('\n');}
    println(val);

when i added into :

        if (arduino.available() >0){
                                  val=arduino.readStringUntil('\n');}

                                  println(val);
                                textSize(18);
                                text(val, 500, 180);

there is an error, and there is written "could'nt run the sketch" and the problem is this section :

            text(val, 500, 180)

help me to solve this problem , how to correct sketch writing if you want to display a string on the run window . Thank you , any help would be greatly appreciated

    text(trim(val), 500, 180);

    or

    text(trim(str(val)), 500, 180);

    Chrisir thank you , I really appreciate your help , and I am very happy . My problem is solved , but new problems arise , I do not know how to change the position of the variable " val " to be in the position I want, this is my code

       ` import controlP5.*;
    import processing.serial.*;


    ControlP5 cP5a;

      }
    }`

    I want to ask is how to adjust the position of " val " to be positioned in the position I wanted.

    text(val, width/2, height/2);

    thankyou...

    so what values do you want?

    look at map() please in the reference
