Oh, please also tell me what I was doing wrong (aside from using duplicate entities).

I'm mainly trying to understand how enities work better, and how functions use them as arguments. I'd really like to know why when you right click and it removes the entity again, thr process couldn't start over. Was I stuck in a loop somewhere? Or can't that removed entity be used again?

If you figured it out, and have the results for me, just PM me with info on the model you want done
