No, still not getting it. When you say user enters C2.name, C3.name
and C4.name do you mean he actually enters the string "C2.name,
C3.name and C4.name" or do you mean he enters actual names or what?
Please give an example of actual records and their fields and values
and exactly what the user might enter and what you want to show.
