If you post a screenshot of the error messages, I might be able to help.
One thing I should mention, there's different modes in Twine for writing, I use the one called Sugarcube, so that's the one I'll be best at helping with
so far I fixed most of the errors but I would appreciate if you could tell me what I could improve in (Its still very unfinished) https://twinery.org/2/#/stories/d72bdd04-8b18-4700-baef-af7bc0e2478c btw im using harlowe, if it helps any I could switch to sugarcube
