math.random not working at all?

I don't know what's wrong with this script.

local Part = game.Workspace.Part
Part.Transparency = 1
while true do
	wait(.5)
	parsttochosefrom = math.random(1,2)
	if parsttochosefrom == 1 then
		Part.Transparency = 1
		end
	if parsttochosefrom == 2 then
		Part.Transpacency = .5
	end

There are a few solutions that could help you. These are them:

• On line 12 put another "end" to end the while loop.

• Throw a math.randomseed(tick()) in there.

• Do elseif rather than another if

Try this code and see if it works:

local Part = game.Workspace.Part
Part.Transparency = 1

math.randomseed(tick()) -- Makes things more random
while true do
	wait(.5)
	parsttochosefrom = math.random(1,2)
	if parsttochosefrom == 1 then
		Part.Transparency = 1
	elseif parsttochosefrom == 2 then -- An elseif here will make the code more smooth and faster
		Part.Transparency = .5
	end
end -- You forgot this end here

	local Part = game.Workspace.Part
	Part.Transparency = 1
	while true do
	    wait(.5)
	    parsttochosefrom = math.random(1,2)
	    if parsttochosefrom == 1 then
	        Part.Transparency = 1
	        end
	    if parsttochosefrom == 2 then
	        Part.Transpacency = .5
	    end

PLEASE MARK THIS HELPFUL, DON'T JUST TAKE SCRIPT AND GO
