Hi there,

You're almost there but what you're doing is echoing a string.

To echo the second value of the array you need to use a whole number like this

echo $colors[1];

Also you used a capital C to reference your $colors array but this doesn't match your original declaration. :-)

It looks like you're really close. You just need to update your formatting:

  • variables/arrays are case-sensitive
  • remove quotes from around the index/number (numbers typically don't need to be wrapped in quotes, unlike strings of text)
  • put your index [1] right next to the array name
  • remove the random slash after your echo statement
<?php
echo $colors[1]; 
?>
