Conditional Formatting in word document - Null fields

I am struggling to write an if then statement for a null condition.  Here is what i am trying to do:

If all fields have content in Salesforce, show this way:

Attendee Name, Attendee Title 

If there is no title in Salesforce, show this way:

Attendee Name 

Here is the code I am putting in Word 

<<Attendee_Attendee_First_Name>> <<Attendee_Attendee_Last_Name>> { IF <<Attendee_Title_Form>> = “” “” “, <<Attendee_Title_Form>>” *MERGEFORMAT}

When I run the report - I get this:

First Last IF Title = “” “” “, Title”

or if there is no title - I get this:

First Last IF  = “” “” “,”

I can't figure out how to write the code in Word.  Any help would be appreciated

Thank you,
