Hi @rachel_a_stender,

Is this for CS Principles (high school) or CS Discoveries (usually middle school, but sometimes high school as well)? The Circuit Playground is a CS Discoveries tool and there’s a whole unit dedicated to it in there.

Can you please let us know what the intended purpose of that line of code is? Can you also tell us what steps you’ve taken so far?

It’s difficult for us to troubleshoot why it isn’t working as you’d like it to, if we don’t know what that is. Telling us what you & the student have tried so far will also help us rule out possibilities.

Thank you,  
–Michael K.
