I may just be setting up my query completely incorrect but my expected result set that I need returned is `Nuestra B & Nosotros B` since they fall into the date range respectively.  I.E. Nuestra B `feeduedate >= '20160301' AND fj.feeduedate <='20160330'` and for Nosotros B `fe.ViolationDate >= '20170601' AND fe.ViolationDate <= '20170606'` they fall into place.

However when I run this query attempting to return the result I get 0 returned in my result set.

What is incorrect with my query?  Below is sample data & DDL

    	CREATE TABLE [dbo].[fei](
