Help with making a simple script? [RESOLVED via adark] [TY adark]

So I am trying to make this brick disappear at random intervals, but idk what to do, because I am a horrible scripter. Any help? Script thus far:

wait(math.random)
script.Parent.Transparency=1
wait(math.random)
script.Parent.Transparency=0

I am trying to make it to reappear randomly and repeat. Can someone help me?

First, put this in an infinite while loop.

Next, choose what you want the minimum time to wait and the maximum time to wait between it vanishing and reappearing.

local maxTime = 2 --in seconds
local minTime = 0

while true do
	wait(math.random()*(maxTime-minTime)+minTime)
	script.Parent.Transparency = 1
	wait(math.random()*(maxTime-minTime)+minTime)
	script.Parent.Transparency = 0
end
