How to choose a part with math.random (random question mark?)

I've seen a lot of people do round based games and use math.random() to choose what spawn the player goes to. I've been running into a lot of trouble with this. Whenever I use it it tells me that whatever number it came up with is not a valid object in spawns.

Script:

local Spawns = workspace.MapStorage.Map:GetChildren()
local chosenmap = math.random(1,#Spawns)

for i, v in pairs(game.Players:GetPlayers()) do
    local name = v.Name
    if workspace:FindFirstChild(name) then
        workspace[name].Torso.CFrame = CFrame.new(workspace.MapStorage.Map[chosenmap].Position)
    end
end

I also have a script that changes the spawns parent so it can't be used again until the end of the round where the main script puts it back.

First you have to make a random number variable.

local RandomMapNumber

Lets say you have 3 maps.

local RandomMapNumber = math.random(1, 3)

Get the maps from serverstorage.

local ServerStorage = game:GetService('ServerStorage')

local map1 = ServerStorage:WaitForChild('map1name')
local map2 = ServerStorage:WaitForChild('map2name')
local map3 = ServerStorage:WaitForChild('map3name')

Next, you have to make a function to choose a random map.

function randomMap()
    RandomMapNumber = math.random(1, 3)

    if (RandomMapNumber == 1) then 
        local map1clone = map1:Clone()
        map1clone.Parent = workspace

    elseif (RandomMapNumber == 2) then 
        local map2clone = map2:Clone()
        map2clone.Parent = workspace

    elseif (RandomMapNumber == 3) then 
        local map3clone = map3:Clone()
        map3clone.Parent = workspace
    end
end

Hope this helped. GL
