Why cant my script find this item in replicated Storage?

We've been talking in the chat feature, I'm just posting here to show you some formatting

--Create a RemoteEvent in ReplicatedStorage, title it what you want
--Server side
local PurchaseGun = game:GetService("ReplicatedStorage").EventName

--Add guns and change prices as you wish.

local GunPrices = {
	["Pistol"] = 100,
	["Revolver"] = 200,
	["Uzi"] = 300
}

PurchaseGun.OnServerEvent:Connect(function(Player, GunName)
local Cash = Player:FindFirstChild("leaderstats").Cash
    if Cash.Value >= GunPrices[GunName] then
        Cash.Value = Cash.Value - GunPrices[GunName] 
        print(GunName)
        print("Bought")
	local clonegun = ReplicatedStorage.Guns:FindFirstChild(GunName)
        clonegun:Clone().Parent = Player.Backpack -- im getting a error that says "clonegun' (a nil value)"
        print("Cloned")
        end
    end)
end)

Then in a LocalScript, parented to the GUI

local PurchaseGun = game:GetService("ReplicatedStorage").EventName
local Buy = script.Parent.BuyButton --Obviously, change this to the location of the button
local Gun = "DefaultGun"

Buy.MouseButton1Click:Connect(function()
	PurchaseGun:FireServer(Gun)
end)

--I am assuming the player uses a GUI to choose the gun type?  In that case, you need to add functions for whatever buttons you are using to choose.  For example,

local RevolverButton = script.Parent.RevolverButton --Change location as needed
RevolverButton.MouseButton1Click:Connect(function()
	Gun = "Revolver"
end)

--If you want the player to just press the gun button, as in the Player presses "revolver" and it attempts to buy the revolver,

local RevolverButton = script.Parent.RevolverButton --Change location as needed
RevolverButton.MouseButton1Click:Connect(function()
	PurchaseGun:FireServer("Revolver")
end)
--This would get rid of the BuyButton function, but you would need to create one of these for every gun.

Any questions, just ask
