Why is my RemoteFunction giving me an error saying, "attempt to call a number value"?

I am currently learning how RemoteEvents, and RemoteFunctions work, and in my game, I want to send an IntValue from the server to a specific client, and update that player's MoneyGui to show the sent IntValue. However, I keep getting an error in the output saying, "attempt to call a number value". Does anyone know why?

Also, I understand the difference between RemoteFunctions and RemoteEvents. RemoteFunctions can send and receive information two ways, while RemoteEvents can only send and receive information one way. I would use a RemoteEvent, except I don't know how to access a value sent from a RemoteEvent.

Here is the code.

Server Script

script.Parent.Touched:Connect(function(hit)
local sendValue = game.ReplicatedStorage.SendValue
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
local storedValue = script.Parent.Parent.storedValue 

    local function returnValue()
        return storedValue.Value
    end

    if player then
        sendValue.OnServerInvoke = returnValue()
    end
end)

Client Script (Inside of a textLabel)

while wait() do
local getValue = game:GetService("ReplicatedStorage"):FindFirstChild("SendValue"):InvokeServer()

    script.Parent.Text = tostring(getValue)
end

I hope this made sense.

Thanks in advance!

The reason it says "Attempt To Call A Number Value" is because of the returnValue function, when we say return it means send back information, so it turns out to be this (from what i know)

sendValue.OnServerInvoke = storedValue.Value

but that causes an error, so we need to make it all in one!

-- {{ SERVER }} --

script.Parent.Touched:Connect(function(hit)
    local sendValue = game.ReplicatedStorage.SendValue
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    local storedValue = script.Parent.Parent.storedValue 

    if player then
        sendValue.OnServerInvoke = function()
        return storedValue.Value
    end
    end
end)

-- [[ CLIENT ]] --

while wait(1) do
    local getValue = game:GetService("ReplicatedStorage"):.SendValue:InvokeServer()
    script.Parent.Text = tostring(getValue)
end

now the reason i put wait(1) in just because it seemed like you kept invoking the remote function a lot lol

It works! Thanks man. I have been trying to figure this out all day. CVDev 2 — 4y

Just curious, if I used a RemoteEvent, and Fired to the Client an IntVale, how would I access the value I fired, from the local script? I am still learning how Events work, and I think it would be easier to simply Fire the Value to the client each time the part is touched. Thanks again. CVDev 2 — 4y

add a parameter called plr, and in that send the players name, then in the server script fire to the client with the player you sent, its a bit of a hacky way Kriscross102 118 — 4y

You don't need to make returnValue an anonymous function, it could stay named as he wanted it. It's just a matter of assigning the function reference, not calling it. i.e. `sendValue.OnServerInvoke = returnValue()` should have been `sendValue.OnServerInvoke = returnValue` EmilyBendsSpace 1025 — 4y

...but, I think there are bigger problems with this code, in terms of how it's meant to work for multiple players. Assigning a remoteFunction's OnServerInvoke more than once is unusual, and almost certainly not what you want here. EmilyBendsSpace 1025 — 4y
