Challenge: Basic JavaScript - Understanding Undefined Value returned from a Function

Link to the challenge:

the tests are checking the value of the sum variable. At the end it should be 8 as the function addThree should run once and the function addFive should run once. The function calls are already included. You have added the quoted line changing the final value of the sum variable, try deleting that line.
