Combine Multiple Records in Crystal Reports

Question

I have a table with our clients buying preferences, The first three columns is the client ID, Name and Last name and the fourth and fifth columns is the clients buying preference, I have multiple records per client depending on the preference the client has chosen.
ID First Name Surname Type Suburb
5 John Smith House Melrose
6 John Smith House Rosebank
7 John Smith House Kilarney
8 John Smith Cluster Melrose
9 John Smith Cluster Rosebank
10 John Smith Cluster Kilarney
I need to combine the fourth column into one string and the same for the fifth column.
ID First Name Surname Property Type Suburb
5 John Smith House, Cluster Melrose, Rosebank, Kilarney
I have been getting closer by using the formula in a similar post,  Combine Field from Multiple Records
but still struggling a bit
Any help with this would be greatly appreciated.

Answer 1

Thank you so much, I was a bit blind there. That works brilliant for one client,
As I was saying yesterday, that was just one client of many in my report, What do I do in the case of multiple clients...
ID     First Name     Surname     Property Type     Suburb
5     John     Smith     House     Melrose
5     John     Smith     House     Rosebank
5     John     Smith     House     Kilarney
5     John     Smith     Townhouse     Melrose
5     John     Smith     Townhouse     Rosebank
5     John     Smith     Townhouse     Kilarney
6     Jack     Black     Cluster     Sandton
6     Jack     Black     Cluster     Houghton
6     Jack     Black     Cluster     Fourways
6     Jack     Black     Appartment     Sandton
6     Jack     Black     Appartment     Houghton
6     Jack     Black     Appartment     Fourways
obviously if I use that formula, with many records the following happens, before I suppress...
ID     First Name     Surname     Property Type     Suburb
5     John     Smith     House     Melrose
5     John     Smith     House     Melrose, Rosebank
5     John     Smith     House     Melrose, Rosebank, Kilarney
5     John     Smith     House, Townhouse      Melrose, Rosebank, Kilarney
5     John     Smith     House, Townhouse      Melrose, Rosebank, Kilarney
5     John     Smith     House, Townhouse      Melrose, Rosebank, Kilarney
6     Jack     Black     House, Townhouse, Cluster     Melrose, Rosebank, Kilarney, Sandton
6     Jack     Black     House, Townhouse, Cluster     Melrose, Rosebank, Kilarney, Sandton, Houghton
6     Jack     Black     House, Townhouse, Cluster     Melrose, Rosebank, Kilarney, Sandton, Houghton, Fourways
6     Jack     Black     House, Townhouse, Cluster, Appartment     Melrose, Rosebank, Kilarney, Sandton
6     Jack     Black     House, Townhouse, Cluster, Appartment     Melrose, Rosebank, Kilarney, Sandton, Houghton
6     Jack     Black     House, Townhouse, Cluster, Appartment     Melrose, Rosebank, Kilarney, Sandton, Houghton, Fourways
obviously if I have to suppress, NOT ONLASTRECORD
I have the following result...
ID     First Name     Surname     Property Type     Suburb
6     Jack     Black     House, Townhouse, Cluster, Appartment     Melrose, Rosebank, Kilarney, Sandton, Houghton, Fourways
Where as the result I desire is
ID     First Name     Surname     Property Type     Suburb
5     John     Smith     House, Townhouse      Melrose, Rosebank, Kilarney
6     Jack     Black     Cluster, Appartment     Sandton, Houghton, Fourways
Is there anything I can do to get this result?
