As others have written, some of the rows of your table do not have graphic
objects.
You need to select all records that *have* a graphic object before you can
update the table.
If you use "Query -> Select" simply type "obj" in the box after the label
"That satisfy:". You can then update the table that results from that
selection
withc CentroidX() and/or centroidY() without any problem.
You probably will want to fill in the coordinate columns for record that
don't have
graphic objects with a "dummy" value (zero will do nicely).
To do that, use "Query -> Select" again, and type "not obj" in the same
place you had
typed "obj" before.
