Am looking to see if it is possible to use Boolean logic on the client letter and organizers to substitute the Salutation field for the Client name field. 

We have clients who are referred to middle names or nick names and these are the names in the salutation field.  When printing letters, to always make sure the client receives correspondence using nicknames (salutation), is it possible to input a logic test to see if the salutation is not blank that the data is used is from the salutation field rather than the client name field?
