Solved An internal error occurred... Help?

[PotatoGoesMoo]

Skript Version: 2.1.2
Skript Author: Njolbrim
Minecraft Version: Spigot 1.8.8

So the problem is, whenever I do the following and reload the skript:

command /bio [<text>]:
    trigger:
        set {bio.%player%} to %arg-1%
        message "&aYour bio has been set!"

It gives me the error message "An internal error occurred while attempting to perform this command". I don't know why this happens, but whenever I remove the [<text>] part I get no errors whatsoever.

Console Stuff:

I am using the addons Skellet 1.8.8, RandomSk 2.7.1, WildSkript 1.8, SkQuery 4.0 Prerelease 2, and SkStuff, if that helps. Thanks!
