Math.random always chooses 0?

This is my script, it always chooses "0", meaning the door's transparency will remain 0. I've tested it many times and it just doesn't seem to ever open the door. I understand random can sometimes repeat but, this is ridiculous. Any help? Do you see any errors I have skipped over in the last hour? Thank you.

sp=script.Parent

sp.ClickDetector.MouseClick:connect(function()
math.randomseed(tick())
sp.Transparency=math.random(0,1)
wait(3)
    if sp.Transparency==1 then
    game.Workspace.givecandy.Value = true
        wait(5)
            if sp.Transparency==1 then
            sp.Transparency = 0
            game.Workspace.givecandy.Value = false
            end
else
    print("not awake")
            end
end)

Again, no errors are shown in output, but if you see any I may have missed anyway please tell me. Or perhaps, I wrote the script wrong? Thank you again..
