Piano Keys (Item 6)




I am stuck at item 6 from the Piano Keys exercise:

At this time my code should work, but when I press the piano keys, nothing happens.

I am attaching to this message a screenshot of my codes from item 1 to 6. Can anyone identify where is my mistake?


I copied and pasted a value with typo from Codecademy instructions. This is what caused the code not to work. It took me hours to find out.
