Thank you, having all these problems and never thought of that
Alright, I've changed everything around so it is now $eveit359. Plugin output is now getting to the template, as long as it's plain HTML. When I try to make $eveit359 into an array (store a value into $eveit359[1], and put that in the template, I get output like "p[charname]". I am completely lost trying to figure out what the heck the template/plugin tutorials are saying with variable renaming or whatever it is they're talking about. I need to have several arrays of data accessible to the template, preferably in one big array $eveit359[1][charname], $eveit359[1][charid], $eveit359[1][tree][current], $eveit359[1][tree][time], etc.
