And again, I'm sorry.
... Sorry, but can I ask for a page deletion again?
I thought that maybe the error occurred last time because I forgot to save it on a page titled as a template. Since that's not the case, I'm guessing that one of the functions I'm using is invalid. Probably fornumargs. I was trying to see if I could get a template to work with a variable/indefinite number of inputs. I'm abandoning the idea after this, so hopefully I don't cause anymore fatal errors.
Done. Does "Show preview" not show the error? If not I would recommend using it when dealing with questionable stuff like this.
It did not. Just the bold text from my test cases, which understandably couldn't show me anything since they were calling a template which didn't exist yet since it was still in preview.
