BackgroundTransparency and ImageTransparency not working in a loop?

Well, basically, I've got a portion of a script that isn't working, when from all I can see, should be. Here's the portion in question --

local hant1 = script.Parent.haunt1.ImageTransparency
local hant2 = script.Parent.haunt2.ImageTransparency
local hant1b = script.Parent.haunt1.BackgroundTransparency
local hant2b = script.Parent.haunt2.BackgroundTransparency
local red = script.Parent.red

for i = 1,10 do
    hant1  = hant1 + .1
    hant1b  = hant1b + .2
    wait(.1)
end

wait(1)

for i = 1,10 do
    hant2b  = hant2b - .2
    hant2  = hant2 - .1
    wait(.1)
end

wait(2.5)

for i = 1,10 do
    hant2  = hant2 + .1
    hant2b  = hant2b + .2
    wait(.1)
end

for i = 1, 3 do
red.BackgroundTransparency = red.BackgroundTransparency + .3
wait()
end

for i = 1, 3 do
red.BackgroundTransparency = red.BackgroundTransparency - .3
wait(.01)
end

This is in a local script, and all of it does run (guaranteed with a print). If you need any more information, please let me know, I've tried to keep this post shorter, but as a consequence, vague.

Thank you for reading, and I hope to find a solution to this strange issue.
