try this:

Code:
 alias CheckIdlers {
  var %chan = #needhelp, %a = $nick(%chan,0)
  while %a {
    if ($ulevel[color:red] ==[/color] 10) || ($ulevel [color:red]==[/color] 11)  [color:red]{ return } [/color] 
    if ($nick(%chan,%a,r).idle > 20) {  
      ban -ku300 %chan $nick(%chan,%a) 2 Please do not idle. Return in a while if you need help or want to help
    }
dec %a
  }
}
