Great job, looks and works nice, and as Kirby said not every one has a channel called that.
If you looking to only have it for your channel try:

on *:TEXT:!present:#:{
if ($chan == your channel)
if ($nick !isop $chan) {
set %gift $rand(1,4)
if (%gift == 1) { msg # 4here's an 7Xbox 360, $nick $+ ! 3Enjoy it while 9it lasts. :) }
if (%gift == 2) { msg # Here's a guitar, $nick $+ ! Start Shredding out! }
if (%gift == 3) { msg # Here's a cookie, $nick $+ ! If you eat it now, I'll eat your head. WAIT TILL CHRISTMAS }
if (%gift == 4) { msg # Here's your high school diploma back, sorry I had to take it, but I needed to get into this sweet party(Jk) }
}
}
}
