David,

Without a link to your challenge, I'm not entirely sure what is being asked of you during this task, but I'm going to venture that you're being told to echo the color green from the colors array? If that's the case, the issue here is that you are trying to call a value from your array at an index called 'green', which doesn't exist. You don't have an associative array here (which would be an array with key => value pairs), you have an indexed array (just values, that live at numeric indices starting at 0). Thus, to call green from your array in this particular situation, you would want to call its index number, which is 2.

echo $colors[2];

Thank you for the link. Now being able to see the task, I can see that it wants you to echo the second value from your indexed array, which would be at index 1 (whereas 2 would echo the third value, which corresponds to green in this instance).

Glad to have been of assistance! Please do make sure you link from the challenge or at least provide a link to it should you need help in the future!

Happy coding!

Erik
