Bouncing Projectiles

Ok, I have seen another thread where is was said that all you needed to make a tower's projectiles bouce is:
(it's not a direct quote but it's what the person had said.)
Anyways I have done so yet this still does not work. It only hits 1 target not 3 (3 is the # I put in)

You need to set the [Combat - Attack X - Area of Effect (Full Damage)] field to a non-zero value. That's the field it uses to determine how far the projectiles can travel when they bounce, and if it's set to zero, there won't be any targets in range, even if it has bounces left.
