Error on Vim

[TenaarFeiri]

So I'm trying to run this on Vim and it works, but it would seem comments aren't being processed correctly?
I'm not familiar enough with Vim to make much more sense out of the error message.

Error detected while processing /home/martin/.vim/syntax/lsl.vim:

Well, this left me rather confused when it arrived in my mailbox.

Lmao sorry! The "lslCommentTodo,@spell" part of it tagged you because I forgot to set it to code initially. Whoops!
