My database contains:
•    Data Entry form that includes fields for Form Number and Form Title
•    Documents Issued subform that has fields for Year, Rev#, Number Issued,
Date Issued, Starting Number, Ending Number, Issued To, Dept Staff,
Reconciled.
•    Documents Issued Table that shows data entered for all of the above fields
except Form Title from Data Entry form and Starting and Ending number fields
from the Documents Issued subform. The latter two fields are populated based
on the Number Issued and Date Issued.

How can I get the Documents Issued Table to show data from all the fields?

If the fields can be calculated based on the values in Number Issued and Date
Issued, then they should simply *not exist* in the table.

Storing derived data such as this in your table accomplishes
three things: it wastes disk space; it wastes time (almost
any calculation will be MUCH faster than a disk fetch); and
most importantly, it risks data corruption. If one of the
underlying fields is subsequently edited, you will have data
in your table WHICH IS WRONG, and no automatic way to detect
that fact.

Just redo the calculation whenever you need it, either as a
calculated field in a Query or just as you're now doing it -
in the control source of a Form or a Report textbox.
