Need help with function (package)

Question

HI,
Here is my scenario
I have a package (stored procedure), and 3 functions and 1 procedure. Procedure calls all the functions to fetch data. I am having a trouble in accessing one of the functions. I need to count the number of records satisfy my where clause. Following is my example.
FUNCTION S_LEVEL (ME_NO IN VARCHAR2, STDATE IN DATE, ENDATE IN DATE) RETURN NUMBER AS LEVEL NUMBER;
SELECT COUNT(*)
FROM --- xS, -- SP
WHERE XS.SRVNBR = SP.NBR
AND XS.MEMBER_NBR = ME_NO
AND ((XS.DIR IN ('2824','28241','28242','5173','28952')
and xs.date between stdate and endate;
RETURN LEVEL;
END s_level
Now when I call this function from procedure (through a Crystal report), it never return anything and just freeze. Could someome please guide me what I am doing wrong or how it is supposed to be done?
Please help me, I will really appreciate your time and efforts.

Khurram,
It's always a bad idea to use a reserved word to name something, regardless whether Oracle allows it or not.
Sooner or later you'll run into trouble.
