How do I update the disount field for all customers who do not already have a
discount?

You can see your table structure - we cannot.

Guessing that there is a field in the table Customers named Discount, you can
create an update query with a criterion

Is Null

on the discount field to find all records with blank (empty) discounts. If the
discount defaults to 0 you can use a criteron

=0

Post back if I'm misguessing your table structure!
 
Update [SomeTable]
SET Discount = .1
WHERE Discount is Null Or Discount = 0

In query design view
== Add your table
== Add the discount field
== Set the criteria to Is Null or <> 0
== Select Query: UPdate from the menu
== In the UPDATE TO "cell" under Discount field enter
.1 (for 10 percent discount)
