In multi-task challenges, you add to the previous code in each step.

It looks like you removed the task 1 code when doing task 2. You need to leave the code you did for task 1, and add code to perform the task 2 instructions to it.

The "Check Work" function will always re-test each previous task in order, so if previous code is removed or altered it will keep you from passing.

Hi there,

It looks like you deleted the code from Task One? All code that you enter needs to be there as the Tasks move on. So, the code above is correct, but the Code Checker will return an error because it's still trying to find the code from the first task.

Hope that helps. :dizzy:
