Converts a carriage-return delimited list to one separated by commas, with the word "and" placed before the last item. I'm expecting that most people will use the List function on a related set of records to generate the items required.

Added a Max Number parameter and an And/Or preference, April 2010.

I get the last value duplicated. For example:

Value1, Value2, and Value2

How do I correct this?

I added the Oxford comma by adding the following line to the case statement:

not IsEmpty ( FirstValues ) and Extras = 0 and CountValues = 2; FirstValues & " " & And_Or_Parameter & " " & LastValue ;

and modified the following case to include the comma.
not IsEmpty ( FirstValues ) and Extras = 0 ; FirstValues & ", " & And_Or_Parameter & " " & LastValue ;

Great CF
