Hi James,

I'm definitely going to recommend you take another look at the video - the answer to the first challenge comes directly from it.

Here's a hint: You're assigning these values to "a" and "b" (using an equals sign). The challenge is just asking you to associate the cases with String (no equals sign needed, and you don't need to make up any particular string values like "a" and "b"). Watch the video again and see if you can figure it out. If not, I'll give you the answer :).
