No, the attribute name is REV1ECN#. No wildcards. Just in case it was my mind playing tricks on me, I copied it straight out of AutoCAD and put it in the script. Could it be that AutoCAD doesn't like the #? Is there a wildcard symbol that I could put in its place so that it would recognize the first part of the attribute name? For instance, would it recognize REV1ECN*? I guess I could change the block to remove it, but that block has been used on thousands of drawings so far.
