Hi,

The solution is to use a boolean value :

```auto
var inserted = false;

if(hands above your shoulder){
  // If you didn't already inserted a number
  if(!inserted){
    // Insert your number here
    inserted = true;
  }
}else{ //Otherwise set inserted to false
  inserted = false;
}

```

Check this example, it works fine (it only adds one element when the mouse is on the upper part of the canvas) :

```auto
var inserted = false;
var array = [];

function setup() {
  createCanvas(400, 400);
  noStroke();
}

function draw() {
  background(220);
  
  fill(255, 0, 0);
  rect(0, 0, width, height/2);
  
  fill(255);
  rect(0, height/2, width, height/2);
  
  text("inserted : " + inserted, 50, 50);
  
  text("array : [" + array + "]", 50, 100);
  
  if(mouseY < height/2){
  // If you didn't already inserted a number
    if(!inserted){
      array.push(floor(random(10)));
      inserted = true;
    }
  }else{ //Otherwise set inserted to false
      inserted = false;
  }
}

```
