Cant really tell whats cause it to warn you, but i guess its caused by nil?

WaitForChild returns Instance?type (aka Instance or nil) instead of Instance type, you need to do something like this

local part = workspace:WaitForChild("Part")

if part then
	for _, surf in Enum.NormalId:GetEnumItems() do
		...
		part[surface] = "Glue"
	end
end

and to be extra safe, typecast Part type to part variable

local part = workspace:WaitForChild("Part") :: Part

From perspective of compiler it doesn’t know what Surface variable represents, it can be anything and this really goes against why we use strict, we use it to make code predictable because of this you have to make sure to tell the compiler its one of the surface properties by type annotation or if statement that checks value of surface matches surface property names. Also when using WaitForChild you have to tell compiler what type its, right now you’re telling compiler to wait for an instance that is called “Part” it doesn’t know what type of instance its, it doesn’t know instance is part.

Assign the Part you are looking for first and assert the type to be a Part, then you can access the surface property without any type errors

local Part = Workspace:WaitForChild("Part") :: Part
Part.Surface = "Glue" --Is surface even a property?

yes
But why you write workspace from upper case?
Anyway please cache it
Next time dont make me suffer having to rewrite it please for god sake

local Part = workspace:WaitForChild("Part")::any

for _,surf in Enum.NormalId:GetENumItems() do
--I aint rewriting allat

end

That not what he wanted

surface is a variable

So surface for example is a “BottomSurface” e.g. Part[“ButtomSurface”]

And it accepts string instead of enum as an option
Althrough its probably bad for performance

Since its a dynamic property lookup you have to cast it to any instead of to part

7

If you cast it dynamically im not sure if strict typing will allow you to access those properties

8

Enum.NormalId is constant, not sure why you need loop.

--!strict

local part = workspace:WaitForChild("Part")
part.BottomSurface = Enum.SurfaceType.Glue
part.TopSurface = Enum.SurfaceType.Glue
part.LeftSurface = Enum.SurfaceType.Glue
part.RightSurface = Enum.SurfaceType.Glue
part.FrontSurface = Enum.SurfaceType.Glue
part.BackSurface = Enum.SurfaceType.Glue
