Microsoft Access Quiz: Hidden Bound Customer ID Fields and Callback Forms

Test your Microsoft Access form skills with an expert-level callback form quiz. The questions cover a deceptively useful detail: hiding a bound Customer ID control does not erase its value or prevent buttons and VBA from reading it.

You will also revisit common callback-list issues, including clearing the Must Callback flag when a call is finished, understanding how date arithmetic changes when time values are removed, and recognizing that a form opened from a filtered query still shows only that query's records.

The episode also tackles a familiar query design headache: duplicate date columns caused by selecting both ContactT.* and a separate Callback Date Time field. A few small form and query choices can keep callback workflows accurate without losing important contact history.
