# Displaying the result of PHP isset function issues in code.

Hi Michael, You have to put if block inside the for loop. That way you will check numbers from 1 -100 and compare them against your array \$facts and if a number matches number from the array a message is printed along with the number. See the code bellow:

```<?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',
);
