No title will work please read? [closed]

I'm currently making a gun shop for my zombie game, but I've run into an issue.

I don't have any experience in remote events, so I was wondering if someone could help me.

This normal script is in ServerScriptService

--Variables--
local Button = script.Parent
local Player = game:GetService("Players").LocalPlayer
local RemoteEvent = game:GetService("ReplicatedStorage").BuyRemoteEvent
local PurchaseButton = script.Parent.BuyPrompt.PurchaseButton
local LeaveButton = script.Parent.BuyPrompt.LeaveButton

--Actual Scripting--
local RemoteEvent = game:GetService("ReplicatedStorage").BuyRemoteEvent
local Item = game:GetService("ServerStorage").Guns.FourthGun
RemoteEvent.OnServerEvent:Connect(function(Player, item)
    if item == Item.Name then
        local Cash = Player.leaderstats.Cash
        if Cash.Value >= 50 then
            Cash.Value = Cash.Value - 50
            Item = Item:Clone()
            Item.Parent = Player.Backpack
            else
            print("Not enough cash")
        end
    end
end)

This local Script is somewhere deep in StarterGUI

--Variables--
local Button = script.Parent
local Player = game:GetService("Players").LocalPlayer
local RemoteEvent = game:GetService("ReplicatedStorage").BuyRemoteEvent
local PurchaseButton = script.Parent.BuyPrompt.PurchaseButton
local LeaveButton = script.Parent.BuyPrompt.LeaveButton

--Actual Scripting--
script.Parent.MouseButton1Down:Connect(function()
    script.Parent.BuyPrompt.Visible = true
end)

LeaveButton.MouseButton1Down:Connect(function()
    script.Parent.BuyPrompt.Visible = false
end)

PurchaseButton.MouseButton1Down:Connect(function()
    RemoteEvent:FireServer("FourthGun")
end)
