It might be better if you were to copy this code into a new JS project and post your question in the "Help Requests" tab. Posting in "Help Requests" allows members of the Khan Academy community to see your full code in the editor and offer help.

To start, on the first line, you are trying to create a new instance of an object that has not been defined. Remember that lines of code are executes in order. You cannot create a `new SmileyFace` before you have told the system what a `SmileyFace` is.

Also, you are defining the `draw` method twice. The second definition has no code inside. This overwrites the previous definition and this method does nothing.

You need to move the first two lines of code after the definition of `SmileyFace` and delete the second definition of `.draw`.
