Autofill Data To A Main Table From A Reference Table

First of all apologies for the lack of proper terminology I'm a novice Ms Access user and I like to thank everyone in advance for trying to help.

Ok here is the situation:

I have two tables, NewJobs and Contacts which have the following fields.

Newjobs
--------
JobID (AutoNumber, Primary Key)
JobName
JobDate
JobDescription
JobOwner (Linked to table 'contacts' via LookUp)

Contacts
---------
DisplayName
EmailAddress
Department
Extension

Ok basically what I want is to have a form based on table NewJobs which will allow me to enter new jobs into the database. When I get to JobOwner a drop down list linked to 'Contacts' table will show me all the data from column 'DisplayName' and allow me to select it (saves time on typing). I have already done this and its not a problem.

Now I would also like in the same form to have additional fields from table 'contacts' such as EmailAddress, Department and Extension which will autofill with the right information soon after I select a JobOwner from the drop down list.

So for example if I select 'Joe Bloggs' Access will automatically fill the additional fields in the form with Joe's information (department, extension etc) from the Contacts table.

I hope all this makes sense. Thank you all for your support.
