The Constructor Meter(Meter, int,int) is undefined.

```auto
import meter.*;

Meter m;

void setup(){
  
  size(500,400);
  background(0,0,0);
  //lets add a default meter
  m = new Meter(this,25,10);// here 25,10 are x,y coords.
  
}

void draw(){
  //give some random values to meter
  int value = (int)random(0,10); //generates random values
  //update the meters values
  m.updateMeter(value);
  //use delay to see the changes
  delay(1000);
  
}

```

Do you have the meter library installed?

Does it still happen after saving your sketch and restarting Processing?

No, once I saved then ran it the problem went away.
