Cool-down for swords special attack animation not working properly?

function onKeyPress(actionName, userInputState, InputObject) --KeyPress function
	local attackanim = hum:LoadAnimation(Tool.specialattack1) --Load animation
	if userInputState == Enum.UserInputState.Begin and cooldown == 0 and swordequipped == 1 then --Conditions to be met
		attackanim:Play() --Play animation
		cooldown = cooldown + 1 --Activate cooldown
		print("Cooldown Added")
	elseif cooldown == 1 then
		wait(5)
		cooldown = 0 --Remove cooldown
		print("Cooldown Removed")
	end
end
game.ContextActionService:BindAction("KeyPress", onKeyPress, false, Enum.KeyCode.R) --If R key pressed do onKeyPress function

So basically I'm trying to make it so that the special attack animation can only be used every 5 seconds, the cool-down works once but then any subsequent presses allows me to spam the animation indefinitely. Help would be appreciated.

Here this should work.

Attack = false

function sAttack() --KeyPress function
    local attackanim = hum:LoadAnimation(Tool.specialattack1) --Load animation
    attackanim:Play() --Play animation
end

function onKeyPress(actionName, userInputState, InputObject)
	if userInputState == Enum.UserInputState.Begin and swordequipped == 1 and Attack == false then --Conditions to be met
		Attack = true
		wait(5)
		sAttack()
		Attack = false
	end
end

game.ContextActionService:BindAction("KeyPress", onKeyPress, false, Enum.KeyCode.R) --If R key pressed do onKeyPress function
