Use an If...then...Else field construction.
{ IF { MERGEFIELD maybeemptyfield } = "" "{ MERGEFIELD nextmergefield }"
"{ MERGEFIELD maybeemptyfield }x
{ MERGEFIELD nextmergefield }" }
Where x is a linefeed or carriage return (Shift+Enter or Enter)
Use Ctrl+F9 to insert each pair of field delimiters {} and Alt+F9 to toggle
the display of field codes
