Remove Null Values from Query Widget Dropdown

dkirkley@belleville.ca_bellevilleGIS

I have a layer of Streets that has a number of Null Values in the Street Name field. I also have the list sorted ascending AC that shows all the blank Street Names First.  Where in the code can you remove these values from the list?

Here is the latest version of my code. No Errors, but it still produces Empty Fields
