"value of type Instance cannot be converted to a number" Warning, How do i fix?

[CaptainTeemukas (TheDarkestSmiler)]

Hello Devs! I Am Making A Customization Feature In My Game, But When I Try To Change The NumberValue, It Gives Me The “value of type Instance cannot be converted to a number”, And i have looked for around an hour and i could not find anything that could help me, So I am making this post.

Server Script (ServerScriptService) :

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ServerEvents = ReplicatedStorage:WaitForChild("RemoteEvents"):WaitForChild("ServerEvents")

ServerEvents.ChangeHat.OnServerEvent:Connect(function(Player: Player, HatNumber)
	local HatValue = Player:FindFirstChild("leaderstats"):WaitForChild("Hat")

	print(HatValue.Name, HatValue.ClassName)
	HatValue.Value = HatNumber
end)

Local Script (Inside A TextButton) :

repeat task.wait(0.25) until game.Loaded or game:IsLoaded()

local Player = game.Players.LocalPlayer
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ServerEvents = ReplicatedStorage:WaitForChild("RemoteEvents"):WaitForChild("ServerEvents")

local HatValue = 1

script.Parent.MouseButton1Click:Connect(function()
	ServerEvents.ChangeHat:FireServer(Player, HatValue)
end)

How Do I Fix This?

Hey! Could you let me know if the print statement within the first script given actually prints information about the value?

Yes It Does,

“HatNumber” is referring to a numberValue. This is an instance. You want its value, which you can get with HatNumber.Value

Remove “Player” when firing changehat event from client

Oh, that was an easy fix, Thanks!
