[Answered] How do you get 3 different numbers between 1 and 6??

I'm trying to get 3 different numbers between 1 and 6. I have no idea why it's not working.

math.randomseed(tick())
local num = math.random(1,6)
print(num)

wait(0.5)
math.randomseed(tick())
local numb = math.random(1,6)
print(numb)

wait(0.7)
math.randomseed(tick())
local number = math.random(1,6)
print(number)


while true do
	wait()
	if number == numb then
		wait(1)
		math.randomseed(tick())
		local numb = math.random(1,6)
	elseif number == num then
		wait(1)
		math.randomseed(tick())
		local num = math.random(1,6)
	elseif num == numb then
		wait(1)
		math.randomseed(tick())
		local num = math.random(1,6)
	else
		break
	end
end

any ideas, thanks in advance.

math.randomseed(tick())
local num = math.random(1,6)
print(num)

wait(0.5)
math.randomseed(tick())
local numb = math.random(1,6)
print(numb)

wait(0.7)
math.randomseed(tick())
local number = math.random(1,6)
print(number)

while true do
	wait()
	if number == numb then
		wait(1)
		math.randomseed(tick())
		local numb = math.random(1,6)
		print(numb.."numb")
	elseif number == num then
		wait(1)
		math.randomseed(tick())
		local num = math.random(1,6)
		print(num.."num")
	elseif num == numb then
		wait(1)
		math.randomseed(tick())
		local num = math.random(1,6)
		print(num.."num1")
	else
		break
	end
end

As can be seen in the screenshot, num and numb = the same number so it went to the if statement and changed the number to 2 but then kept going??

math.randomseed(tick())
local num = math.random(1,6)
print(num)

wait(0.5)
math.randomseed(tick())
local numb = math.random(1,6)
print(numb)

wait(0.7)
math.randomseed(tick())
local number = math.random(1,6)
print(number)

while true do
    wait()
    if number == numb then
        wait(1)
        math.randomseed(tick())
        numb = math.random(1,6)
        print(numb.."numb")
    elseif number == num then
        wait(1)
        math.randomseed(tick())
        num = math.random(1,6)
        print(num.."num")
    elseif num == numb then
        wait(1)
        math.randomseed(tick())
       	num = math.random(1,6)
        print(num.."num1")
    else
        break
    end
end

This is the answer (facepalm) I put local in front of the variables in the while true just delete them and it works sorry for wasting your time.
