Thanks Will! Can't do the attribute/layout name. We use one layout per drawing (so only one sheet per drawing) and the layout name is supposed to be "Layout1". Company wide programs look for "Layout1", so I couldn't change that.
Would be nice to be able to link them, but I think the only way to link attributes would be with a reactor, but that wouldn't help with this. My company will not be using this block, unless I use it within the drawings I create/modify, as it's not in the standard library, and I'm not sure the consultants we use would know how to use it.
