I think that would simply be
"VENDOR SS#/ FEDERAL TAX ID#:¶" &
not IsEmpty ( Tab Name::SSN ) ; "xxx-xx-" & Right ( Tab Name::SSN ; 4 ) ;
not IsEmpty ( Tab Name::Tax_ID_Number ) ; "xx-x" & Right ( Tab Name::Tax_ID_Number ; 6 )
Thanks! Worked perfectly. I thought I tried that one, but my syntax must have been off somewhere.
