[Solved] how to make a player have a jump timer?

local hum = script.Parent:WaitForChild("Humanoid")
local holding = false
local cooldown = true

local function cool()
	cooldown = false
	wait(1.2)
	cooldown = true
end

script.Parent.Humanoid.Changed:Connect(function(p)
	if p == "Jump" then
		if cooldown and not holding then
			hum.UseJumpPower = true
			holding = true
			cool()
		else
			hum.UseJumpPower = false
		end
	end
end)

game.ReplicatedStorage.Jump.OnServerEvent:Connect(function()
	holding = false
end)

on the bottom it is fired when the player lets go of the space and this script used to work but when i made the player be a custom character it stopped working like the use jump power no longer had control over the character is there a way to have control over the player again?

edit i made do .JumpPower = 0 to make it not jump and .JumpPower = 50 to make them jump!
