Failing Lab Functions

Lab asks to

Move all code related to launch rocket sequence to a function named launch_rocket . Then call the function and pass in command line argument $1 as function argument so that you can run the script in the format create-and-launch-rocket lunar-mission

but although script works, when sumbitting it fails.
Am I missing something?

Hello, @msgeek
I believe it’s launch_rocket not launch-rocket.
