Problem is most likely the "PLC Address" index into the spreadsheet is
marked "N/A" in the program's "Spreadsheet/Table Column" setup subdialog. If
set to N/A then it seems to cause this problem. Also make sure that your
single unit PLC symbol that you want to pop in is NOT a block insert. It
needs to be exploded so that the attribute definitions are visible,
otherwise you end up with a "nested" block. If you have to explode it to get
this right, also make sure there is not a WD_M block also included on the
drawing. Blow any WD_M block away and purge the drawing (turn ATTMODE to 2
and do REGEN to make this WD_M visible (at 0,0)).
