Hi sg_FHwue,

I have added to your code so that (i think) the number of rectangles in each frame is saved into lastTen[9]

lastTen[] keeps track of the total number of rectangles for each of the last 10 frames with number 9 being the most recent frame and number 0 being the oldest. I have commented out your println and added a new println that displays the total number of rectangles in the last 10 frames. So you may need to change that back depending on what you want to do with it.

I hope this helps.
