Problem executing stored function

Thanks for taking the time to read this.

I have a stored function created by user A that works fine for user A. However, user B cannot 'see' this function from his SELECT. User A granted EXECUTE privileges to a global role that all users belong to. User A also created a PUBLIC synonym for the stored function. An example follows:

        SELECT qty_of_trading_instr_executed(100) FROM DUAL;

User A returns the correct value. User B gets:

    PLS-00201: identifier 'QTY_OF_TRADING_INSTR_EXECUTED' must be declared

I've also tried prefacing the function name with the schema name. Any ideas as to what I'm doing wrong? BTW, I'm using Oracle 7.1.3 and PL/SQL 2.1.3. Thanks
