Attempt to index nil with "FireServer()"

[Kittylitterking123]

Hello! So I am currently trying to make a meme gun and I’m attempting to do so using RemoteEvents, and my experience with them is not that great.

I keep getting this error: attempt to index nil with 'FireServer' whenever my tool is activated.

Client:

local tool = script.Parent
local RemoteEvent = tool:FindFirstChildOfClass("RemoteEvent")

tool.Activated:Connect(function()
	RemoteEvent:FireServer()
end)

Server:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Memes = ReplicatedStorage.Memes

local tool = script.Parent
local RemoteEvent = tool:FindFirstChild("RemoteEvent")
local Handle = tool:FindFirstChild("Handle")

RemoteEvent.OnServerEvent:Connect(function(Player)
	local RandomMeme = Memes[math.random(1, #Memes)]:Clone()
	
	local function FireMeme()
		RandomMeme.Anchored = true
		RandomMeme.Position = tool.Handle.Position + Vector3.new(0, 0, -5)
		RandomMeme.Parent = workspace

		local BodyVelocity = Instance.new("BodyVelocity")
		BodyVelocity.Velocity = tool.Handle.CFrame.LookVector * 50
		BodyVelocity.Parent = RandomMeme

		task.wait(5)
		RandomMeme:Destroy()
	end
end)

If you think you know what went wrong, please let me know! Thank you and have a wonderful day!

It looks like the client isn’t finding the remote event. Try changing the local RemoteEvent value to tool.RemoteEvent or tool:WaitForChild("RemoteEvent") and also make sure the remote event’s name is RemoteEvent

It is not finding the RemoteEvent in this line:

local RemoteEvent = tool:FindFirstChildOfClass("RemoteEvent")

Try a different way using a WaitForChild.

Using :WaitForChild() worked! For some reason, it didn’t before. But now, the memes don’t fire from the tool’s handle.

FireMeme()

Are you calling the function anywhere? In the remote event you’re just defining it
