Hi Masango, there are a few things to it.

First you have to keep the echo $number; you added in previous step, then after that line add the if statement. You also should use the $number as the key for the array, like $facts[$number]. And you were missing a parentheses to close the statement. Finally, you echo the array with $number as key. Se the code below.

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

Hie Filipe, thank you so much for your assistance. I had been vexed by the code. I greatly appreciate your help. You are great in coding, may GOD's favour fall upon you in everything you do. Happy coding!!!!!!
