Using Arduino Programming Questions

Hi,

I am relatively new to Arduino and I'm working on my first project. I am trying to make a Sound Visualizer, and the code keeps reading the same error message.

Here's a link to the code:

https://learn.sparkfun.com/tutorials/addressable-rgb-led-music-and-sound-visualizer

The code is contained within the programming section of the webpage. The problem arises with the last line of code.

Attached is an image of the error code that I have been unable to resolve. Please help!
