Adding Table To Query

My form is based on a select query. There are 2 combos that filter the data displayed in the form by status and property. All of the data is contained in the same table and the query is looking at just the one table. Clicking a button opens a listbox that contains all of the filtered data and clicking a record in the listbox populates the form with that record and closes the listbox. It works good like this.

When I try to add one field (labor) from a second table to the query with that same field added to my form, as long as there is a value in the labor field in the table then it works. If there is no value for labor then the form returns no records. There are records there but they do not have labor assigned yet. I set a default value for the field on my form - (not assigned yet). The listbox displays the records even though there is nothing in the labor field, but clicking a record in the listbox returns an error of 'no current record'.

Actually I dont even have to add the labor field to the form, just having it in the query mucks up the form. I must need an isnotnull statement in the criteria or something.......


Any ideas what I may be doing wrong?

Thanks!
