for each loop and copy stamp question

[waltt]

Hi, i'm new here, been lurking for a while. Hope i'm posting this in the right place.
Still learning houdini while trying to build a procedural house.
Now I've come to a problem that i can't seem to solve, altough it's probably something easy,
I'm still missing some of the basics probably..

Anyway, did some copy stamping of a box across a line, then copy stamped that result across another line.
Now I was trying to run a boolean over every box with a for each loop (like in this video) around the 39 min mark,
but the problem is the loop doesn't see 63 seperate boxes, but 21 times 3 boxes,
so eg I can't scale each box on it's local axis.

Probably has something to do with group names, but i tried everything over the last 2 days and nothing came up
I attached a simplified file with the issue. Any help would be greatly apreciated!

As you say the problem is the name attribute (every name is repeated 3 times). To see it woeoking just put an Assemble node with "create name attribute" checked before the for loop

Thank you so much for the reply! Not sure why it works but it does, need to read up on the assemble node. 
Something slightly related: when i do a boolean in the loop it works ok, altough the result isn't individual objects anymore, some parts are welded together if i try to transform them individually with a primitive node.
Any ideas? Anyway thank you again!
