Reports :: Show Salespeople With 0 Sales Within Date Filter?

I want a very basic report that shows:* all field reps (sales people),

* their quota in terms of new customer registrations

* their actual new customer registrations for a particular month

The report should include field reps with 0 sales. The query I've created works fine as long as there's no date filter. But adding <1/1/2013 removed all field reps with 0 sales. I want to make sure the filter concept was working before getting into date ranges.

Code:
SELECT DISTINCTROW tbl_ksFieldRep.salesRepName, tbl_ksFieldRep.quota, Count(tbl_customers.dateRegistration) AS NewRegistrations
FROM tbl_ksFieldRep LEFT JOIN tbl_customers ON tbl_ksFieldRep.[salesRepName] = tbl_customers.[ksFieldRep]
WHERE (((tbl_customers.dateRegistration)<#1/1/2013#))
GROUP BY tbl_ksFieldRep.salesRepName, tbl_ksFieldRep.quota;
