Hello again, Jack. I'm not sure what your code looked like before or looks like now but I think maybe a different way of helping you out with this is in order. Here's some code that does what I think you're going for and runs:
https://gist.github.com/corasaurus-hex/1c86b545644b734310a15d984f61ad99 Have a look, play with it a bit, change around value and see what breaks. Hope that's helpful!
