Code:
menu status {
  .rooms
  ..$submenu($popupmenu($1))
}
alias popupmenu {
  var %rooms = #IRC-SHACK,#TEST,#MIRC
  var %x = 1
  while (%x <= $numtok(%rooms, 44)) {
    var %r = $gettok(%rooms, %x, 44)
    if ($1 == %x) return %r : join %r
    inc %x
  }
}


needed a return on this line ; if ($1 == %x) return %r : join %r
