WARNING: This program has a logic error, so we have to debug it.
RULE: Every function needs to be called in order to execute. This includes the main function.
Click Run and you will see that nothing happens on the stage.
Fix the program so that the stage will be set. Note: Make sure every function is called!
Click Run to test if you fixed the program. When it is fixed, click Submit and Next.

Are you already running a Codesters project in another tab or window?
Micro:bit can only connect to one web page at a time.
Try stopping other Codesters projects or closing
other tabs or windows that may be using your Micro:bit.
If that doesn't fix the problem try disconnecting your Micro:bit,
reloading this page, and reconnecting your Micro:bit.
