[ENTER].
If you wish to see all the available values in your database, press
[ALT]-[V] to pop up a scrolling window of the values. You may select
one of these by highlighting it and then press [ENTER], or you may
press [ESC] to exit without selecting anything.

you have embedded an open parenthesis in your query.
Ending the query
----------------
When you are finished building the criteria for this query, select
<<DONE>> from the Boolean operator window. You will then be asked to
enter a description for this query for future reference. The
description may contain up to fifty characters. Press [ENTER] when you
are finished entering the description, and you will be returned to the
query window. If you want to exit without saving this query press
[ESC].
If you wish to run this query immediately without saving it for future
use, simply leave the description empty and press [ENTER].
