Coroutine halting midway through code. Any help?

I'm working on a script that will handle certain stats for a game, and wrote a coroutine to handle one of those stats (they must work separately), but it is halting midway through the code. I used tags to debug the block but can't find what exactly is producing this, as I get no error messages nor does the code have any syntax errors. Any help will be appreciated.

The code stops running just before the commented line (it is not commented on the real code). All variables not defined here refer to integer numbers, all correctly defined earlier in the code.

coroutine.resume(coroutine.create(function()
	while true do
		local mindMax = math.ceil(50 + mag.Value/5) + 250 * lv.Value
		if mind.Value < mindMax/10 then
			local waitTime = 2 - (dex.Value + mag.Value)/240
			if waitTime > 1 then
				wait(waitTime)
			else
				wait(1)
			end
--			mind.Value = mind.Value + mindMax/50
		elseif mind.Value < mindMax then
			mind.Value = mind.Value + mindMax/50
		elseif mind.Value > mindMax then
			mind.Value = mind.Value - (mindMax - mind.Value)
		end
		wait(1)
	end
end))
