Summon tree-wall trigger

I don't why but the search function doesn't work at my place so here goes:

Action - Destructable - create summer tree wall at (target point of ability being cast) facing (random angle) scale 1.0 variation 0.
Problem is that it only summons 1 tree. How do I make it summon more? I tried changing variation but with no effect.

that action can only create 1 destr. (or doodad, dunno what it creates)
so you'll have to either loop, or just copy paste more of that action.

if you wanna make it a wall youre gonn have to offset it, or if youre gonna have it trap someone like the ability in DotA id suggest you use a polar offset

Just making a wall. Thnx for the help I'll try it out.
