i did that through anchor object settings friends
Could it be that the anchord object in question won't move because you have it set to keep within margins which is preventing the move you're requesting? I've certainly run into that.
I've also run into the situation where the object model thinks the anchored object is in one place when it is actually in another because of that same keep within margins option. In this case, a move will apparently not work because the move is invisible, it being completely outside of the margins -- although that only applies to relative moves, I think.
By the way, move only takes two arguments. I'm not sure what you expect that true argument to do. It is ignored I believe.
