Why is my combat script only letting one person attack at a time?

My combat script works completely fine when one person is using it, however it starts to fall apart when other players get involved. For some reason whenever I do a combo they cannot do theirs and for me it's the same. And if we somehow are able to do a combo we just end up finishing the other players combo. I honestly don't know how I've managed to do this but if I could get some help it would be greatly appreciated :)

Local Script

Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()
Character = Player.Character
Remote = game.ReplicatedStorage.RemoteEvent
Enabled = true
Action = "Combat"

Mouse.Button1Down:Connect(function()	
	local Player = game.Players.LocalPlayer
	local Character = Player.Character
	if Enabled == true then
	Remote:FireServer("Combat", Character.HumanoidRootPart.CFrame*CFrame.new(0,0,-2).p, "Left")
	end
end)


Mouse.Button2Down:Connect(function()
	local Player = game.Players.LocalPlayer
	local Character = Player.Character
	if Enabled == true then
	Remote:FireServer("Combat", Character.HumanoidRootPart.CFrame*CFrame.new(0,0,-2).p, "Right")
	end
end)
