I've had those settings on and it's still not working. Perhaps I'm not explaining it correctly, so here's a view of the layout I'm trying to achieve:
The text itself
is right-aligned and the box is set to grow with it, but the issue is that the right side is the side that's moving no matter what. I think it's because the object's alignment is locked on the left side (because all positioning is in relation to the top left corner).
I want the right edge to remain locked on the line below it's right edge and for the text to flow right as the page numbers increase. Make sense?
