So, really noobish question, but I can't seem to fully understand what it is I'm missing from the following code to output a link to the streamers name after the command !caster <name> is put into the chat, any help would be appreciated.

Code:
on $*:text:/!caster /Si:#majeye:{
  msg $chan GO FOLLOW THIS STREAMER twitch.tv/$2 $+ 
}

-Majeye
