Isset function introduction

So I don't know how to do this, because the output is exactly what the instructions ask for and the codes works in both the preview and the shell provided. Is there something hidden that I need to do?

index.php 
<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
    2 => ' is the approximate hours a day Giraffes sleeps',
    18 => ' is the average hours a Python sleeps per day',
    10 => ' per cent of the world is left-handed.',
    11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
    98 => '% of the atoms in your body are replaced every year',
    69 => ' is the largest number of recorded children born to one woman',
);

//add your loop below this line
for ($i = 1; $i <= 100; $i++) {
  if (isset($facts[$i])) {
    echo $i;
    echo $facts[$i];
  }
}

?>

the first echo should be before the isset function like this :

for ($i = 1; $i <= 100; $i++) {
      echo $i;
  if (isset($facts[$i])) {
    echo $facts[$i];
  }
}
