SQL - Union Query To Combine 3 Queries

I have three queries that make a training list based on a person's role, team, and ad-hoc exceptions. The personnelID field is filtered by a listbox on a form. Each of these work great on their own (nice!). Now I want to combine them. I made the below union query that works... however when it is run, I am prompted to enter the personnelID again. This prompt only happens once. Do I need to incorporate a qhere statement somewhere, even though each of the individual queries have them already?

SELECT First_Name, Last_Name, TrainingTitle, PersonnelID
FROM qryPersonnelTrainingByRole
UNION ALL
SELECT First_Name, Last_Name, TrainingTitle, PersonnelID
FROM qryPersonnelTrainingByTeam
UNION ALL SELECT First_Name, Last_Name, TrainingTitle, PersonnelID
FROM qryPersonnelTrainingByAdHocPersonnel;

The where statement of potential use:

Code:
WHERE (((tblPersonnel.PersonnelID)=[Forms]![frmMain]![lbxPersonnel]));
