String scalar Function in ms sql2005

Question

Can someone  help me with a function?
I have some sql:
  SELECT depositReceivedCurrency ,SUM(depositReceivedAmount) AS currencyAmount
    FROM    dbo.tbTrades
     WHERE clientID = 1 AND  depositReceivedCurrency IS  NOT NULL
      GROUP BY depositReceivedCurrency
That returns a table like so:
EUR    35459.00
GBP    1000.00
Note: there could be more than 2 currencies
I would like a function that would take this table and out put a string like this:
"EUR    35459.00 / GBP    1000.00"  [ + / ith currency amount]
Possible? here's a chance to show off

Answer 1

I've removed the stuff for simplicity and this gets me what I want:
    SELECT   ( (
SELECT  ' ' + depositReceivedCurrency + ' ',
        CAST(SUM(depositReceivedAmount) AS VARCHAR) + '   '
FROM    dbo.tbTrades
WHERE   clientID = 1
        AND depositReceivedCurrency IS  NOT NULL
GROUP BY depositReceivedCurrency
                                FOR
                                  XML PATH('')
the string
EUR 35459.00    GBP 1000.00    USD 324.00 
however if I do this:
  DECLARE @ResultVar VARCHAR
    SET @ResultVar = (
    SELECT   ( (
SELECT  ' ' + depositReceivedCurrency + ' ',
        CAST(SUM(depositReceivedAmount) AS VARCHAR) + '   '
FROM    dbo.tbTrades
WHERE   clientID = 1
        AND depositReceivedCurrency IS  NOT NULL
GROUP BY depositReceivedCurrency
                                FOR
                                  XML PATH('')
    select @ResultVar
I get nothing
