Why is this function that starts at Line 14 not registering?

You forgot to close the function

local part = Instance.new("Part",workspace)
part.Name = "Bruh"
part.Anchored = true
part.BrickColor = BrickColor.new("Really red")

function say_hello()
    print("Hey there")
end

if part.Name == "Bruh" then
    say_hello()
end

function test_Anchored()
    if part.Anchored == true then
        print("This part is Anchored")
    end
end; -- You forgot this end.

    local part = Instance.new("Part",workspace)
part.Name = "Test"
part.Anchored = true
part.BrickColor = BrickColor.new("Dark stone grey")
part.Size = Vector3.new(4,4,4)

Hope this is what was wrong and that this helps, if it does, please accept this answer.
