2. Drawing multiple squares - instructions unclear

**Issue description:**
A clear and concise description of what the issue is.
In Goals, the instructions say "We already created draw_square() for you." So I didn't include this in my code block. When I ran it, I received the error that draw_square() was undefined. I had just created this function in the previous step, so I could have easily kept it in the code area. It would be helpful if the instructions said to keep the draw_square() function in the code area. Or give the option to create it anew. Saying that "We already created draw_square() for you" made me think I did not need to include it. Thanks!
