FIELD Contact := @If(Contact != @GetDocField($Ref; "FirstName") + " " + @GetDocField($Ref; "LastName") ; @GetDocField($Ref; "FirstName") + " " + @GetDocField($Ref; "LastName") ; Contact);
FIELD OfficeFax := @If(OfficeFax != @GetDocField($Ref; "OfficeFax") ; @GetDocField($Ref; "OfficeFax") ; OfficeFax );
FIELD Company := @If(Company != @GetDocField($Ref; "Company") ; @GetDocField($Ref; "Company") ; Company);

P.S. it has a Hide If formula that is similar

Contact = @If(Contact != @GetDocField($Ref; "FirstName") + " " + @GetDocField($Ref; "LastName") ; @GetDocField($Ref; "FirstName") + " " + @GetDocField($Ref; "LastName") ; Contact)

OfficeFax = @If(OfficeFax != @GetDocField($Ref; "OfficeFax") ; @GetDocField($Ref; "OfficeFax") ; OfficeFax )

Company = @If(Company != @GetDocField($Ref; "Company") ; @GetDocField($Ref; "Company") ; Company)
