Cooldown to prevent msg spam?

[iMinePixels]

I would like some help. I am wanting a cooldown for the pvp message to the attacker so they cannot sit there and spam their chat.
I've tried following a post called cooldowns for dummies, but it just wasn't working out.

on damage of player:
    victim is a player
    attacker is a player
    if world of victim is not "spawn":
        cancel event
        play sound "ENTITY_VILLAGER_NO" to attacker
        send "&7PVP is not enabled here!" to attacker

options:
    cooldown: 5 seconds

cooldowns: map

on damage of player:
    victim is a player
    attacker is a player
    if world of victim is not "spawn":
        cancel event
        play sound "ENTITY_VILLAGER_NO" to attacker
        if {cooldowns::%attacker%} is not set:
            send "&7PVP is not enabled here!" to attacker
            set {cooldowns::%attacker%} to now
        else:
            if {cooldowns::%attacker%} > now - {@cooldown}:
                stop
            send "&7PVP is not enabled here!" to attacker
            set {cooldowns::%attacker%} to now

Try this
