If the screenshot is unclear, here is her code:

var SmileyFace = function(FF,PP) {
this.centerX = FF;
this.centerY = PP;
};
SmileyFace.prototype.draw = function() {
fill(248, 122, 255);
ellipse(this.centerX, this.centerY, 150, 150);
fill(0, 0, 0);
ellipse(this.centerX-30, this.centerY-30, 20, 20);
ellipse(this.centerX+30, this.centerY-30, 20, 20);
noFill();
strokeWeight(3);
arc(this.centerX, this.centerY+10, 64, 40, 0, 180);
};
SmileyFace.prototype.Speak = function(hi) {
text(hi,this.centerX-34,this.centerY+90);
};
var faceObj = new SmileyFace (100,200);
faceObj.draw();
faceObj.Speak("Hi! I'm Bob!");

Is there any extraneous code below line 24?

No - we tried deleting all the extra empty lines, and that made no difference, either.

Try changing `faceObj` to `face`.  It is possible that the auto-grader is set to reject `faceObj` because the object literal was supposed to be replaced by the constructor.

Mystery solved:
So I went over the assignment with her from the beginning, and it turned out the auto-grader wanted her to use

this.centerX = x 

this.centerY = y 

instead of FF and PP (she just said she wanted to be creative and not have a single letter because it was boring... now she knows that boring is okay sometimes...)
:)

The auto-grader can be a little mysterious.  It accepts some things and not others.

Glad you were able to figure it out.
