Forums Scripts & Popups Testing for two things at once (if this and this)

I'm trying to make a subscriber hype for Twitch that displays a different message when the number of months is greater or equal to 12. I would imagine it would be pretty easy.

on *:TEXT:*subscribed*:#:{
if ($nick == twitchnotify) { msg $chan Thanks for subscribing $1! }
}


I know it would be something like: if ($4 >= 12) {msg $chan More than a year! PogChamp } else ...sub hype...

but I am not sure where to put it in regards to the original sub hype.
