RemoteEvent not working?

Okay so, I'm trying to get a projectile to not do any damage to the person shooting it. At first I got it to work inside of studio, but it wouldn't work when playing. I was told to try using RemoteEvents, and I did. For some reason, the way I did it, I'm able to get the server script to return a local player's name, but it only works once. The rest of the time, the event returns nill. Could someone help me? What's in the local script:

local variable cooldownFS = 1
local mouse = game.Players.LocalPlayer:GetMouse()
function shootFS()
	if cooldownFS == 1 then
		print("Works")
		cooldownFS = 0
	local fireballs = Instance.new("Part")
	fireballs.TopSurface = "Smooth"
	fireballs.BottomSurface = "Smooth"
	fireballs.BrickColor = BrickColor.new("Really red")
	fireballs.Transparency = 0.3
	fireballs.Size = Vector3.new(2,2,2)
	fireballs.CFrame = game.Players.LocalPlayer.Character.Torso.CFrame *CFrame.new(0,0,-6)
	fireballs.Parent = game.Workspace
	fireballs.Anchored = true
	fireballs.CanCollide = true
	local damage = script.Damage:clone()
	damage.Parent = fireballs
	damage.Disabled = false
	local mesh = Instance.new("SpecialMesh", fireballs)
	mesh.MeshType = "Sphere"
	local fire = Instance.new("Fire", fireballs)
	fire.Heat = 8
	fire.Size = 20
	local re = Instance.new("RemoteEvent")
	re.Parent = game.Workspace
	re.Name = "re"
	re:FireServer(game.Players.LocalPlayer.Name)
	local bv2 = Instance.new("BodyVelocity")
	bv2.maxForce = Vector3.new(math.huge,math.huge,math.huge)
	bv2.velocity =  (mouse.Hit.p-game.Players.LocalPlayer.Character.Torso.CFrame.p).unit*60
	--game.Players.LocalPlayer.Character.Torso.Anchored = true
		for i = 1,13 do
		fireballs.Mesh.Scale = fireballs.Mesh.Scale +Vector3.new(0.5,0.5,0.5)
		wait()
	end
	bv2.Parent = fireballs
	fireballs.Anchored = false
	wait(2)
	--game.Players.LocalPlayer.Character.Torso.Anchored = false
	fireballs:Destroy()
	wait(1.5)
	cooldownFS = 1
	end
end
script.Parent.Activated:connect(shootFS)

Here's the server script:

wait()
local enabled = false
local re = game.Workspace.re
re.OnServerEvent:connect(function(name)
	 Own = name
end)
print(Own)
function Damage(hit)
	local h = hit.Parent:FindFirstChild("Humanoid")
	local t = hit.Parent:FindFirstChild("Torso")
	if t then
		script.Parent.CanCollide = false
	end
	print(Own)
	if h and not enabled and h.Parent.Parent.Name ~= Own then
		enabled = true
		for i = 1,10 do
			h.Health = h.Health - 2
			wait(1/15)
		end
	end
	enabled = false
	wait(3)
	game.Workspace.re:Destroy()
end
script.Parent.Touched:connect(Damage)
