Solved.

I cant undestand this junk code, sorry.
Why do you have this much statemenets?

Why not just redefine the values of the variables, and at the end just return it with math.random?
And if you need true randomness:

function totallyRandomRandom(first, second)
    math.randomseed(math.random(0, getTickCount())+getTickCount())
    return math.random(first, second)
end

local last
function getRandom(first, second)
	if second > first then
		local rand = math.random(first, second)
		if rand == last then
			return getRandom(first, second)
		end
		last = rand
		return rand
	end
	return false
end

This will get a random number between first and second, making sure its not the same as the last random number you got as well as making sure that its a valid math operation. I hope this helps.
