How do you pass a bool from client to server by Remote Event?

I'm trying to make a tool that has to be charged first before being able to damage.

Client:

local tool = script.Parent

local remoteEvent = tool.RemoteEvent

local charged = false
local canDamage = false

tool.Activated:Connect(function()
	if not charged then
		charged = true
	end
end)

tool.Deactivated:Connect(function()
	if charged then
		remoteEvent:FireServer(charged)

		wait(1)
		charged = false
	end
end)

Server:

local tool = script.Parent

local remoteEvent = tool.RemoteEvent
local blade = tool.Blade

remoteEvent.OnServerEvent:Connect(function(player, command)
	if command then
		blade.Touched:Connect(function(hit)
			local humanoid = hit.Parent:WaitForChild("Humanoid")
			humanoid:TakeDamage(100)
		end)		
	end
end)

What it does is, it still damages even way after charged has been set to false. And we don't want that. I need it to only damage when it's only charged.
