The second part of this question states to:
2.Then use echo to output $languages.
So I use the following code:
Not only does it not allow me to print my array but, when I replace echo $languages with echo $languages it gives me the following error:
Oops, try again. It looks like you printed 'HTML/CSS'--that's one of the original elements! Make sure to print your modified element.
This means the directions in #2 are incorrect and should state "Please print your changed array slot with echo."
