Subquery in cursor

Question

Hi, I'm using the below cursor
CURSOR C3 IS
    SELECT SUM(decode(art_currency,:cp_currency,
    NVL((ART_BAL_LDR-ART_BAL_LCR)/art_ex_rate,0),
    NVL((ART_BAL_LDR-ART_BAL_LCR)/ (Select Cur_Exrate From Currency_Master
                                    Where Cur_Company = :P_Company
                                    And Cur_Code = :cp_currency
                                    And Trunc(Cur_Eff_Date) <= Art_Doc_Date
                                    AND   cur_status = '0' and rownum = 1),0)))
    FROM
     AR_TRANSACTIONS
    WHERE
                    ART_COMPANY=:P_COMPANY
    AND ART_CODE=:CUM_CODE1
    AND ART_DOC_DATE<:P_FROM_DATE;For this i'm getting error : Encountered the symbol 'SELECT' When expecting....
I'm using this in reports6i
Any fix?
Thanks

Ya, the same query works in sql developer.
But in reports it is not supporting.
Thanks for understanding that, I want a redefined query for report.
I tried
     CURSOR C3 IS
    SELECT SUM(decode(art_currency,:cp_currency,
    NVL((ART_BAL_LDR-ART_BAL_LCR)/art_ex_rate,0),
    NVL((ART_BAL_LDR-ART_BAL_LCR)/ Cur_Exrate ,0)))
    FROM
     AR_TRANSACTIONS,CURRENCY_MASTER
    WHERE
                    ART_COMPANY=:P_COMPANY
    AND ART_CODE=:CUM_CODE1
    AND ART_DOC_DATE < :P_FROM_DATE
    And Cur_Company = :P_Company
    And Cur_Code = :cp_currency
    And Trunc(Cur_Eff_Date) <= Art_Doc_Date
    AND   cur_status = '0'; This was working until they defined one more exchange rate for same currency.
Now the query doesnt work anymore, works -- but it calculates for both the exchange rate, so for every one record, i'm getting 2 instead.
I want to take only the most recent ex rate, based on the Art_Doc_Date(<=)
Any help?
Thanks
