Help with a query

I am working on a search system, that allows admins to return very specific data. The most important part of the search is returning a certain columns results as a list. The problem I have is this.

When I run my test, I get an array of stuctures output like this.
1
struct
ADDRESS 1222 W Baseline Road
AGENTLIST Patrick Richardson
COE 05/31/2005
FILENUM S051990
MLSNUM [empty string]
PRICE 158875
STATUS Closed
2
struct
ADDRESS 1222 W Baseline Road
AGENTLIST Jason Robinson
COE 05/31/2005
FILENUM S051990
MLSNUM [empty string]
PRICE 158875
STATUS Closed

But I need the returned output to look like this.
1
struct
ADDRESS 1222 W Baseline Road
AGENTLIST Patrick Richardson,Jason Robinson
COE 05/31/2005
FILENUM S051990
MLSNUM [empty string]
PRICE 158875
STATUS Closed


I have tried looping over the results and creating a list based on the returned objects from the query. But it only places the first record int he list and outputs that only.

This is my current code that I am trying below. Can someone give me a hand with this?
