Heres the script that is in the button to activate the script in ServerScriptService:

script.Parent.MouseButton1Click:connect(function()
	game.ReplicatedStorage.EquipEvents.Equip1:FireServer() 
end)

Then heres the script that gives it to you in ServerScriptService:

game.ReplicatedStorage.EquipEvents.Equip1.OnServerEvent:connect(function(player)
    local char = player.Character
	local item = game.ReplicatedStorage.Items:FindFirstChild("Pizza")
	if player.leaderstats.Pounds.Value >= 25 then
	if not player.Backpack:FindFirstChild("Pizza" ) then
		if not char:FindFirstChild("Pizza") then
			item:Clone().Parent = player.Backpack
			end
		end
	end
end)
