Hi guys, i have a simple script, but this don't work. And i can't find the error. The script should timeout users from which the name begins with Mark (like Mark12345 or Mark15)

Code:
on *:TEXT:*sex*:#*: {
  if ($nick >= mark*) {
    msg $chan /timeout $nick 600
  }
}


The Script works but everyone who write sex will be timed out not just the Mark's

Any Idea?

Thanks

Mike
