Why does my script.Parent Transparency not work?

for i = 1,100 do
wait(0.01)
	script.Parent.BackgroundTransparency = script.Parent.BackgroundTransparency + 0.01
	script.Parent.TextTransparency = script.Parent.TextTransparency + 0.01
	script.Parent.Parent.Stand.BackgroundTransparency = script.Parent.Parent.Stand.BackgroundTransparency + 0.01
	script.Parent.Parent.Stand.TextTransparency = script.Parent.Parent.Stand.TextTransparency + 0.01
	script.Parent.Parent.Desc1.TextStrokeTransparency = script.Parent.Parent.Desc1.TextStrokeTransparency + 0.01
	script.Parent.Parent.Desc1.TextTransparency = 	script.Parent.Parent.Desc1.TextTransparency + 0.01
	if script.Parent.Parent.StandClass.BackgroundTransparency < 1 then
		script.Parent.Parent.StandClass.BackgroundTransparency = script.Parent.Parent.StandClass.BackgroundTransparency + 0.01
		script.Parent.Parent.StandClass.TextStrokeTransparency = script.Parent.Parent.StandClass.TextStrokeTransparency + 0.01
		script.Parent.Parent.StandClass.TextTransparency = script.Parent.Parent.StandClass.TextTransparency + 0.01
	end
	end

For some reason, "StandClass" and "Desc1" turn transparent, but "sit"(which is script.Parent), doesn't turn transparent. I don't know if it is ROBLOX or me, but it doesn't work no matter what I try. Is there something wrong?

You should use variables and functions to shorten your code.

function fade(label, t)
	label.BackgroundTransparency = t
	label.TextTransparency = t
	label.TextStrokeTransparency = t
end

local label = script.Parent
local container = label.Parent
for t = 0, 1, 0.03 do
	-- from 0 to 1 by 0.03
	wait(0.03) -- can't wait for 0.01
	fade(label, t)
	fade(container.Stand, t)
	fade(container.Desc1, t)
	if container.StandClass.BackgroundTransparency < 1 then
		-- This if seems redundant since it ought to be true?
		fade(container.StandClass, t)
	end
end

This should affect them all equally.

Are you sure you aren't misinterpreting which object the not-transparent thing is (e.g., some frame in the background perhaps?)
