Why is my dropper code not working? It's meant to make meshes but it doesn't!

wait(2)
workspace:WaitForChild("PartStorage")

local MeshRandomizer = {1,2} --How every many meshes you have 

----Mesh IDs------
local MeshRandomizer1 = "http://www.roblox.com/asset/?id=430070121" --After =, put the ID of the mesh
local MeshRandomizer2 = "http://www.roblox.com/asset/?id=430355436" --Same thing here. You can put as many MeshRandomizers as possible.

while true do
    wait(1.5) -- How long in between drops
    local part = Instance.new("Part",workspace.PartStorage)
    part.BrickColor=script.Parent.Parent.Parent.DropColor.Value
    part.Material=script.Parent.Parent.Parent.MaterialValue.Value
    local i = math.random(1, #MeshRandomizer) --Sets the random value
    local mesh = Instance.new("SpecialMesh",part) --Creates the mesh
    if MeshRandomizer[i] == 1 then
        mesh.MeshId = MeshRandomizer1
    elseif MeshRandomizer[i] == 2 then
    mesh.MeshId = MeshRandomizer2
end
    local cash = Instance.new("IntValue",part)
    cash.Name = "Cash"
    cash.Value = 5 -- How much the drops are worth
    part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.4,0)
    part.FormFactor = "Custom"
    part.Size=Vector3.new(1.2, 1.2, 1.2) -- Size of the drops
    part.TopSurface = "Smooth"
    part.BottomSurface = "Smooth"
    game.Debris:AddItem(part,20) -- How long until the drops expire
end
