Help with SQL statements please.... URGENT PLEASE!!!!

Question

I have 2 Tables
TABLE_NAME COLUMN_NAME DATA_TYPE
TASTEWINE TWDATE DATE
TASTEWINE BIN NUMBER
TASTEWINE QUANTITY NUMBER
TASTING TDATE DATE
TASTING PLACE VARCHAR2
a) Table TASTING has 2 columns.... TDATE( date Tasting was Held) and PLACE ( locations at which Tasting was held)
b) Table TASTEWINE has 3 Columns.............. TWDATE( wine tasting date, BIN( ID number for type of wine that was tasted), AND QUANTITY( quantity of win consumed by bottles)
Here is the QUestion.... I am having a hard time figuring out how to connect those two tables based on this information .. What I want to do is this.....select the total number of bottles of wine served at each wine-tasting, but only for the second half of the year 1999, and I want to see not only the date and total bottles served, but also the location where the wine-tasting took place. I also want to display the date, the place, and total quantity.
Can Anyone please Help me??

Hi,
Your query works fine - as well as the one mentioned by Alok. I have tired it with some sample values, and both show the same results:-
The two tables :-
CREATE TABLE TASTEWINE
     TWDATE     DATE,
     BIN     NUMBER,
     QUANTITY NUMBER
CREATE TABLE TASTING
     TDATE DATE,
     PLACE VARCHAR2(100)
);Rows in the Tables:-
INSERT INTO TASTEWINE VALUES (TO_DATE('01/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('02/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('03/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('04/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('05/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('06/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('07/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('08/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('09/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('10/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('11/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('12/12/1999','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('01/12/2000','MM/DD/YYYY'),1,100);
INSERT INTO TASTEWINE VALUES (TO_DATE('02/12/2000','MM/DD/YYYY'),1,100);

COMMIT;The First Query :-
