Something else that I missed before - in the ForEach version, you had a "on ForEach loop" condition where you needed a "on ForEach loop for object" condition (the main problem is still what I said before though).
Anyway, the ForEach extension appears to do something screwy with the object scope (seems like a bug to me, but maybe it's just a "feature") - you can work around it easily enough though, by throwing in a single fastloop to reset the object scope the way it should be (so you have a ForEach loop inside a Fastloop, inside another ForEach loop).
