WARNING: This program has a bug, so we need to fix it! Let's learn some function rules!

RULE 1: Function names cannot have any spaces in them. Combine two word names with an underscore _ , like this: function_name.

• Click Run and read the error message.
• Debug the program by making the function name one word.
