Naveed.

I do not think you are understanding the answers you are getting and why the
solution may be simple in your mind but it is not simple for a database to
understand.

Your Purchase table...
SNO Item Serial Starts Serial Ends
1 Talk home 87564561 87565060


Your Sales table
SNO Item Serial Starts Serial Ends
1 Talk home 87564581 87564590
2 Talk home 87564640 87564690

Normally in a Purchase table (or what we would here describe ans in
Inventory table) you would have a Quantity or Stock column which would let
you know who many items you have in stock or how many items had been
purchased. Then in the Sales table there would be a couln to indicate
QuantitySold. You could then easily do a query to show the amount sold and
update your Purchase table to deduct the amount Sold thereby creating an
updated Quantity in your Purchase table.

However, because of the way you choose to set up your tables the *only*
solution that comes to mind is creating a query (name it qryPurchases...

SELECT Purchases.SNO, Purchases.Item, Purchases.[Serial Start],
Purchases.[Serial End], Val([Serial End])-Val([Serial Start]) AS OnHand,
Left([Serial Start],5) AS MatchTo
FROM Purchases;

Then for you next query (name it qrySales)...

SELECT Sum(Val([Serial End])-Val([Serial Start])) AS Sold, Left([Serial
Start],5) AS MatchTo
FROM Sales
GROUP BY Left([Serial Start],5);

And for you final query (you can name that what ever you like)...
SELECT qryPurchases.SNO, qrySales.MatchTo, qryPurchases.Item,
[OnHand]-[Sold] AS Balance
FROM qryPurchases INNER JOIN qrySales ON qryPurchases.MatchTo =
qrySales.MatchTo;

However, it should be noted, the above will only work if the data is like
what you provided, if not then the queries have to be redone. And I will
stress that *this* solution is NOT the way it should be done. You really
need to consider the *great* advice you have already gotten that your tables
need to be restructered to fit a normalized database design. What you are
doing is forcing a square peg in a round hole.

Good Luck!

i reallly appreciate your help thanks for all of you but still let make
it
more clear i am not satisfied what i want ....... let make it more clear
i
will have two tables; one for purchases and the second for sales to give
you
the idea about the stock .

for example [purchases table]
SNO Item Serial Starts Serial Ends
1 Talk home 87564561 87565060





which are 500 cards in the stock. if i sell the cards randomly such as 50
and 10 so what would be the stock serial in hand then.

SNO Item Serial Starts Serial Ends
1 Talk home 87564581 87564590
2 Talk home 87564640 87564690

however there are two transaction now in the sale table where in the
first
transaction i sold 10 cards while in the second transaction i sold 50
cards
so the question is that how i would know in the system that which cards
serial number are in my hand when slowly i sale more cards.
hopefully it is more clear now

thankx in advance

thanks for the reply i already know what you told me but i am
confused
about
the question i have asked it could you please the serial number in my
example
then you will know understand yourself that what i mean and that
can't be
done through match or unmatch queries. that's why i am
saying a
challenge for everybody to sort it out

thankx

Using your example, create a table with the numbers 1 to 100. Create
an
unmatched query using the unmatched query wizard that includes that
table
and your sales table that contains the serials you sold. The
unmatched
query
will return the serials in the 1 to 100 table that are not in your
sales
table. To create an unmatched query, open to the list of queries and
click
New. One of the options will be to open the unmatched query wizard.
