You made some typos, and have completely missed the point of tables and loops. That's not terrible or something, it just mean you have something to learn. I'm going to fix some things, and hope you'll understand it. If you have questions, please ask them. p.s. you can write your code between

Second, I'm going to give you the same tip I posted for someone else in another thread, but it's a lot of text so here's a link:

Your use of rectangle1, rectangle2, rectangle3, ..., rectangle6 and a separate rectangleList is kind of a wasteful way of doing things. Instead follow my tip in the link above. You will not have to code as much.

Also, yes, please use the
