How could I get this to work? (Roblox Lua)

Question

So, recently I have become interested in creating a worthy and fun Roblox game. I decided to add a cool feature, where if you go into your assigned room, it will kill your player. Sadly, the code I have currently doesn't seem to work. Example:

local Display = script.parent.Frame.TextLabel.Numberdisplay

number.Value = math.random(101, 113)

Door = "Door"

local numby = Door.. number.Value
Display.Text = number.Value
local player = game:GetService("Players").LocalPlayer

local Shop = workspace.numby

Shop.Touched:Connect(function(hit)
    if hit.Parent == player.Character then
        player.Character.Humanoid:TakeDamage(1000)
    end
end)

Any form of help would be great. :)

Answer 1

I don't know where you got player from but if that's the issue try this:

Shop.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") then
    hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - 9999
end

end)

could you also explain what numby is?

Answer 2

After mixing together @actravaz 's and @Luke100000 's code the door thing worked. Thankyou guys for all your help. :) Answer code:

local number = script.Parent.Value
local Display = script.parent.Frame.TextLabel.Numberdisplay
number.Value = math.random(101, 113)
Door = "Door"
local numby = Door.. number.Value
Display.Text = number.Value
local player = game:GetService("Players").LocalPlayer

local Shop = workspace[numby]

Shop.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - 9999
    end
end)
