Query design question

[MLH]

I have tblClusters containing names of corporations. I have tblAdmin
containing individual store names. Each cluster can have many stores
in tblAdmin. I have tblVehicleJobs containing automobile records.
Each store in tblAdmin can have many related records in tblVehicleJobs

tblClusters has ClusterID as its keyfield. tblAdmin has TowCoID as its
keyfield and ClusterID as a link field to tblClusters. tblVehicleJobs
has VehicleJobID field as its keyfield and TowCoID as a link field to
the vehicles table.

Whew! Having said that, the vehicles table has a boolean field named
[BilledOut]. What I want to do is extract a dynaset showing each
Cluster for which at least 1 vehicle in the vehicles table has a
[BilledOut] field value of False.

In other words, if I had a hundred corporations in the Clusters table,
but there were only 3 vehicles in the vehicles table having a
[BilledOut] field value of False, I would want to see ONLY those
corporations in the dynaset related to those 3 cars. Can this be done?

I think I've got it, but I'd like a second opinion...

SELECT DISTINCT tblClusters.ClusterName
FROM (tblClusters INNER JOIN tblAdmin ON tblClusters.ClusterID =
tblAdmin.ClusterID) INNER JOIN tblVehicleJobs ON tblAdmin.TowCoID =
tblVehicleJobs.TowCoID
WHERE (((tblVehicleJobs.VehicleJobID) Is Not Null) AND
((tblVehicleJobs.BilledOut)=False))
ORDER BY tblClusters.ClusterName;
