Can't find my mistake :(

<?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 $facts = $i; for($i = 1; $i <= 100; $i++){ echo $i . "<br/>\n"; }

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
$facts = $i;
for($i = 1; $i <= 100; $i++){
    echo $i . "<br/>\n";
}

Hi there, Neven Shtiliyanov! First, and foremost, you are completely overwriting the $facts array with essentially a null because $i is not defined at this point. But you don't want to overwrite facts at all.

So start by removing $facts = $i;

Your for loop is starting at 1 and going up to 100 (inclusive). What we want to know is if $facts[1] has a value. It doesn't. But $facts[2] does.

There should be a check inside your for loop on $facts[$i] to see if it isset. If it is set, echo out $facts[$i]

Hope this helps! :sparkles:
