Required Data In A Row-SQL Server 2000

Hello,
I am trying to get results in one row from the following function but all records does not come from the following function.
I have 9 records of the same empid but results not showing all records. Can anybody help me to get all records with the fields and table which I am using.
My table is beneficiary and fields are empid int, fname char(40), benefittype char(4) and benefitpercentage .
Following function is working but problem is not getting all results in one row, as described below.

CREATE FUNCTION dbo.GetBenefString5
(
@Empid INT
)
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE @ret VARCHAR(8000)
SELECT @ret = ''
SELECT
@ret = @ret + CASE WHEN LEN(@ret) > 0 THEN ',' ELSE '' END + FName + ' ' + Benefittype + ' ' + BenefitPercentage
From Beneficiary

Where Empid = @Empid
RETURN @ret
END

SELECT
Empid,
dbo.GetBenefString5(Empid)
FROM pf25eaton_work.dbo.eaton_chr_benef_05052008
where EmployeeNumber='4500498'
GROUP BY Empid


Result from the above function query:
Empid ----------- ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1773 CHARLENE OLIF 33 ,CHARLENE EADD 33 ,CHARLENE ELIF 33 ,TIMOTHY EADD 33 ,TIMOTHY

(


Records are in the table: (But I have many records like that so definitely I will need counter/function etc to get these data.
FName Benefittype BenefitPercentage
---------------------------------------- ----------- -----------------
CHARLENE OLIF 33
CHARLENE EADD 33
CHARLENE ELIF 33
TIMOTHY EADD 33
TIMOTHY ELIF 33
BRADLEY ELIF 33
TIMOTHY OLIF 33
BRADLEY OLIF 33
BRADLEY EADD 33

Desired Result in one row:

Charlene OLIF 33, Charlene EADD 33, Charlene ELIF 33, TIMOTHY OLIF 33, TIMOTHY EADD 33, TIMOTHY ELIF 33, BRADLEY OLIF 33, BRADLEY EADD 33, BRADLEY ELIF 33
