Not Showing Blank Values On A Report

Hi,

Each client has either an entry with a correspondence number or a notes number. So, the table would look somewhat like this:

Client: 333, Correspondence: 1, Notes: Blank
Client: 333, Correspondence: 2, Notes: Blank
Client: 333, Correspondence: Blank, Notes: 3
Client: 333, Correspondence: Blank, Notes: 4

How would I make a report that will make it look like this

Client: 333, Correspondence: 1, Notes: 3
Client: 333, Correspondence: 2, Notes: 4

Thanks! Hope that was clear.

G
