Summary of corrections to "Running Microsoft Access" and the
PROMPT.MDB database as of 1/24/93.

To properly display totals when some months have no sales for
a particular item, the formula should read:

     +IIf(IsNull([Mar]),0,[Mar])


Chapter 19, Pages 424-426, "Orders Form Properties" and
"Picking a Customer on the Orders Form"
Although setting Allow Updating to Any Tables does let you update
customer information on the "one" side of the query as documented,
it also has the unwanted side effect of attempting to delete the
customer row when you try to delete an order.  This works OK when
you are deleting the last order for a customer (but the customer
row disappears!), but generates an error if the customer still has
orders outstanding.  The sample database has been changed to set
Allow Updating to Default Tables.  The desired update to customer
information is accomplished with unbound controls and additional
macro routines in the Orders macro.

Improvements to PROMPT.MDB:

OnDelete macros have been added to all forms in the application to
trap all possible referential integrity violations and display a
more informative message box or take appropriate cascading delete
action.

A macro has been added to BeforeUpdate of the Display / Add Components
form to cause any change in Our Cost to also be reflected in any
related rows in the Catalog Items table.
