Why can't I use turnRight?

I’m getting the following message when I click “Finish” in bubble 2 of lesson 3.6.

But I don’t understand why…turnRight was introduced in the last lesson. I don’t see any instructions that say that we can only use moveForward and turnLeft. What am I doing wrong?

The command set is limited to the blocks available in the tool box. In lesson 5, one of the activities was to create a function called right() as opposed the valid Javascript command turnRight(). The goal is to develop an appreciation for top-down design and function design. So, you are welcomed to define and use a function to turn right. Just don’t call it turnRight().

Happy computing,
