Hi i need help putting a limit on how many tickets a user can buy. For ex. they buy 10 tickets but they can continue to use the command to buy more i need it so that 10 tickets is the maximum tickets they can buy. thanks in advance

on *:TEXT:!buytickets &:#:{
  if (%raffle == 1) {
    if ($2 > 10) {
    msg $chan Sorry $nick but you can only buy up to 10 tickets.    }
    if ($2 < 11) {
      var %i = 0
      var %ticket = $2
      var %topic = $+(#,.,$nick)
      var %user = $readini(Points.ini,%topic,Points)
      var %end = 10 * %ticket
      var %delete = %user - %end
      if (%delete > 0) {
        writeini -n Points.ini %topic Points %delete
        while (%i < %ticket) {
          write Raffle.txt $nick
          %i = %i + 1
        } 
        msg $chan $nick you have bought %ticket tickets with %end points!
      }
