prohibit nonstop entering and exiting a region

[xRiuse]

The region named "x" can be entered once, I want it to be entered maximum 6 times.
I want it to write something like "you can repeat in x seconds" when you enter after 6 .

I'm not sure if this event can be canceled

on region enter:
  if "%event-region%" contains "x":
    if {regionnum::%player's uuid%} is less than 7:
      add 1 to {regionnum::%player's uuid%}
    else:
      cancel event
      send "nah"
