Spawn function not working? [ANSWERED]

So, I made this script what includes a for loop.

The spawn function (doors1) should run the function but also go onto the (doors2) function aswell, for some weird reason, it's just running the (doors1) function and waiting for the function to finish before it goes onto the (doors2) function. What am I doing wrong?

function doors1()
    FOR LOOP
end

function doors2()
    FOR LOOP
end

spawn(doors1())
print "test"
spawn(doors2())

Thanks!
