Tools doesn't work when online only playing in solo?

All I know is that when I select the tool for this instead of being able to use it and 'upgrade' your skills, it breaks when you select it. It works fine when i'm editing in studio and play solo, but when I go to play it normally it doesn't Print anything when selected and it just says " Image unable to load : Unexpected URL "

local bin = script.Parent

function round(num, idp)
	local mult = 10^(idp or 0)
	return math.floor(num * mult + 0.5) / mult
end



function onButton1Down(mouse)
	local player = game.Players.LocalPlayer
	if player == nil then return end

	points = player.leaderstats["Stat Points"]
	type = bin.Type.Value
	upg = player.stats[type]
	cost = math.floor(upg.Value ^ 1.45 / 10) + 1
	if(points.Value < cost) then return end
	if(upg.Value >= 4999) then return end
	upg.Value = upg.Value + 1
	player.leaderstats["Level"].Value = player.leaderstats["Level"].Value + 1
	points.Value = points.Value - cost
	bin.Name = type .. ": " .. upg.Value
end

function onSelected(mouse)
	print("select")
	mouse.Button1Down:connect(function() onButton1Down(mouse) end)
end

bin.Selected:connect(onSelected)
