I hate the Alamo

Yeah this is my first map, so please forgive my horrible newbishness. As you may have read earlier I am trying to create an Alamo type scenario where the player is assaulted by enemies that keep spawning a short distance from their base. Only problem is that the bad guys just sit where they spawn no matter how many different ways I tell them to attack. I have no idea what is wrong here and I'm just about ready to s,ash my comp to bits. Any help would be greatly appreciated and will save the life of an innocent computer. My AIM sn is A Clockwork Noah. ....god I feel pathetic

Have you told spawned units to AI - Ignore Guard Positions? They'll faithfully return back to where they came from if you don't. Also, units created for Neutral Hostile tend to sit around anyway; give them to an actual player if you want them to behave normally.
