Strange Spawning

[Raveren]

Ok, I will explain : ) Im making a Hero siege. Im using this tutorial: http://www.thehelper.net/forums/showthread.php?t=45616 *Andrewgosu, You are great at explaining*
And here is a problem. I want to repeat spawn 10 times for every level, I will explain:
I have Lesser Demon. Its for Level 1, and I want to spawn 5 Lesser demons, wait 6 seconds, and spawn 5 lesser Demons again and again and again... After minute I want to change Lesser Demon to Tiny Skelly - lvl 2. And again, 5 Skellys, wait 6 seconds, 10 times. How to do that?

If-then? If time = w/e, summon w/e.
