Need to create mailing labels using Mail Merge Wizard In xubuntu. Addresses are not populating from database

I create a spread sheet of addresses, create the database, then attempt to use the mail merge wizard to put the addresses on a document so I can print them onto peel and stick labels. No matter how many times I go through the steps that are supposed to populate the document, I can’t get it to work.

I am begging! PLEASE HELP ME!!!
