The multi-part identifier "CourtesyCars.carreg" could not be bound.

Hi

I have been working on trying to convert this query from Access to SQL Server for the past day and am still having trouble. Im almost there, but am still getting the following error message on the query below:

The multi-part identifier "CourtesyCars.carreg" could not be bound.

I can see why Im getting this, but cant seem to rectify it. Any ideas?

Cheers
