in the aliase section I have
/away /me [Not here, back in a few hours]
The problem is - that you've replaced /away command with your alias.
And it's not setting you away, so the $away and other stuff will not work.
Try to replace your alias with this:
/away {
me [Not here, back in a few hours]
.quote away [Not here, back in a few hours]
}
