Change of character/Break of structure help needed...

[johnwood34]

I've had chatgpt adjust this and adjust that, about twenty times in an attempt to debug what it created. Anyone out there can help me with this? I know nothing about programming/thinkscript. If you need any clarification on what i'm trying to accomplish, please just ask. I'll also provide a link to a script i found here that has Change of character(CHOCH)/Break of structure(BOS) incorporated into.
