For some reason I can't get this to work. It works fine until I try to make it a mod only command. What's weird is it was working fine yesterday but not today. I haven't changed it at all either.

Code:
on *:text:!on:#: {
  if ($nick !isop #) return 
  .timer.timername 0 1500 msg # test
}

on *:text:!off:#: {
  if ($nick !isop #) return 
  .timer.timername off
}


Any help would be greatly appreciated.
