Formula Column help please - URGENT

Question

I'm trying to create a formula column as follows:
function NO_REPLIESFormula return Number is
NOREPLY number;
begin
SELECT COUNT(reply) INTO NOREPLY
FROM letters
WHERE reply = 'N'
GROUP BY ltrtype, batch;
RETURN (NOREPLY);
end;
This PL/SQL compiles fine, but when I run the report, I get the following messages:
REP-1401 no_repliesformula FATAL PL/SQL error occured. ORA-01422 exact fetch returns more than requested number of rows.
If I remove the GROUP BY ltrtype, batch, I don't get the error messages, but the result I get is the total no_replies instead of the total no_replies for each ltrtype/batch grouping.
Could someone please help me with this?
Thank you.

Hi irish,
I think i am not sure about what you are trying to say, but let me guess, You want the values to be return on the bases of "ltrtype, batch". Which mea that you want more then one values, i mean there can be more then one Groups based on ltrtype and batch. and you want to display these values with repective record???
If i am right, then there is a fault in your code, and that is , you are not specifing in your code that which value is to be diplayed with which record in this report. For that there must be ltrtype, batch colums displayed in the report, you must add those values in your Code in the query, i.e.
function NO_REPLIESFormula return Number is
NOREPLY number;
begin
SELECT COUNT(reply) INTO NOREPLY
FROM letters
WHERE reply = 'N' and ltrtype= :V_ltrtype and batch=:v_batch;
RETURN (NOREPLY);
end;
Where :V_ltrtype and :v_batch are the run time values of each records displayed in the report.
Remember that if you don't sepecify this then your code will return as many records as many distich values of ltrtype, batch. and your variable NOREPLY can hold only one value at a time. I hope you understand both, Solution and the logic behind the error.
Please correct me if i am wrong.
Thanks.
