Hello everyone I'm new on this discussion page, my name is Gevo and I am in need of assistance. I have been messing around with a script I found off of a website and I thought it looked really neat so I thought I can give it a try. So far everything was going ok, until grasshopper started to show some errors and I have no idea why. I have a feeling there are hidden expressions that I am not aware of. If anyone can help me figure this script out I would be greatly appreciative. 

Below is are a series of compiled images as follows:
