Why is "Decal is not a valid member of Part" occuring?

Okay please take note

--------------------Model

---------Brick

--------------Decal

---------Brick

--------------Decal

---------Brick

--------------Decal

---------Brick

-------------Decal

That is what my model looks like, I have this code



local orderboard = game.Workspace.ModelCollection:GetChildren()
local ID = game.Workspace.ReferenceDecal.Texture

for i, v in pairs(orderboard) do    
      if v.Decal.Texture == ID then 
        ---extra stuff goes here
      end
end

I keep getting the error

Decal is not a valid member of Part

Why is this? Shouldn't the for loop be able to iterate things inside of the brick?

It seems like one of the Parts in ModelCollection doesn't have a Decal.

Check if the descendant has a decal, before attempting to index it.

local orderboard = workspace.ModelCollection:GetChildren()
local ID = workspace.ReferenceDecal.Texture

for i, v in pairs(orderboard) do
    local Decal = v:FindFirstChild("Decal")
    if Decal then --Check if it exists
        if Decal.Texture == ID then 
            ---extra stuff goes here
        end
    end
end

That was it, thank you so much you are very good. I never thought about putting checks to see if these exist in the for loops or if statemetns. Thank you truly, I had some bricks in the model that did not have any Decals and I did not notice that. Seyfert 90 — 7y
