Well, I am not a scripter (yet) and have little to no skill at it. I am trying to do this with the stats editor using the AoEConditions part of the skill to add a min / max area that the zombies can spawn in. More than most likely I am doing this completely wrong. I used this in the AoEConditions box:

GetRandomBetween (OUT INT|FLOAT variable, INT|FLOAT 3.0, INT|FLOAT 8.0)

If someone could give me a starting point of where to learn what it is I need to do, that may be more helpful in the long run, as well as easier on you guys. Although I won't turn down someone downright walking me through it lol.
