# Cant access an variable out of a loop? Help please

Tell us what’s happening:
Hey, ive got a problem with this exercise. Exactly with the fact that my code add the biggest values to the array largestNumbers in the loop, BUT when i want to actually extract that variable largestNumbers with its array out of the loop then, well, i cant… I cant understand why, can anybody explain?

``````
function largestOfFour(arr) {
// You can do this!
var largestNumbers = [];
var largest = -100000;
for (var i = 0; i <= arr.length; i++) {
for (var j = 0; j < arr[i].length; j++) {
if (arr[i][j] > largest) {
largest = arr[i][j];
}
}
largestNumbers.push(largest);
largest = -100000;
console.log(largestNumbers);     // here it shows the array correctly [25,48,21,-3]
}
console.log(largestNumbers);           // here i cant acces it, help pls
return largestNumbers;

}

largestOfFour([[17, 23, 25, 12], [25, 7, 34, 48], [4, -10, 18, 21], [-72, -3, -17, -10]]);

Hey, thanks. i corrected it to `for (var i = 0; i < arr.length; i++)` and now it works.
