Exercise 6, Step 7

I thought I'd put this up in case anyone else came across the same initial problem I did....
______________________

Step 7 in the exercise states, [ Select a record in table "owners.dbf", what do you see in table "attributes of parcels.shp"? ]

I thought "Select a record in the table "owners.dbf" simply meant clicking on the beginning of the row in the table.  By simply doing this, nothing happened in table "attributes of parcels.shp".  After reading chapter 9, I figured out that "Select a record in the table "owners.dbf" actually means
  1. Clicking on the beginning of the row in the table, then
  2. Going to the bottom of the table and clicking the "Selected" button.
By doing the above two steps, something does happen in table "attributes of parcels.shp"....however, I did not see it until I did the following::
  • Still in table "owners.dbf", scroll to the bottom of the table and click on the "options" button.
  • Select Related Tables
  • Parcels
Then, I noticed that the record in parcels.shp changes to match the record you originally selected in "owners.dbf".

I tried in the opposite direction too (selecting a record in the "parcels" table and seeing what happens in the "owners" table), with similar results.
