When you have a multiple @If to eliminate NULLS there may be a better way: 
 @If( LotusNotesName != "" ; LotusNotesName ;                               
             @If( LegalName != ""; LegalName :                              
                      @( NickName != ""; NickName; "Old what's his name"))) 
                                                                            
                                                                            
 @Subset(@Trim( LotusNotesName:LegalName :NickName);1)

This will return the first non null from you list.
