Cannot find texture ID player is wearing?

Hi,

I am attempting to operate a t-shirt/shirt only door at which only operates when someone has the correct clothing on. I think this is the older way of performing the task of collecting the texture ID that someone is wearing and wanted to know the new way to get this to work? The links there are correct so it's just helping the script find the texture the player is wearing?

print ("VIP T-Shirt Door Script Loaded")


permission = { "kieranm9090" } 


first = "http://www.roblox.com/asset/?version=1&id=412190047" 
premiumeco = "http://www.roblox.com/asset/?version=1&id=412190012"



function checkOkToLetIn(name) 
    for i = 1,#permission do 

        if (string.upper(name) == string.upper(permission[i])) then return true end 
    end 
    return false 
end 

local Door = script.Parent

function onTouched(hit) 
    print("Door Hit") 
    local human = hit.Parent:findFirstChild("Humanoid") 
    if (human ~= nil ) then 
        if human.Parent.Torso.roblox.Texture == first or premiumeco then 
            Door.Transparency = 1 
            Door.CanCollide = false
            wait(4)  
            Door.CanCollide = true 
            Door.Transparency = 0 

            print("Human touched door") 

        elseif (checkOkToLetIn(human.Parent.Name)) then 
            print("Human passed test") 
            Door.Transparency = 0.7
            Door.CanCollide = false 
            wait(4) 
            Door.CanCollide = true 
            Door.Transparency = 0  
        end 
    end 
end 

script.Parent.Touched:connect(onTouched)

Many thanks, Kieran
