Since you are saving the winning numbers and the ones you picked, there's no need to "save" how many numbers match. You can do this via a query and then just reference the query when you need that data.
Your table of numbers should look like this:
tblNumbers
num_ID, autonumber primary key
ID_Drawing, number, foreign key to tblDrawing which holds data about the drawing these numbers are for
num_Value, number, the actual value of the number
num_Type, text, this determines if the number was a number chosen by you ("Played") or a winning number of the drawing ("Winner")
So that 1 table will hold both your guesses and the winners for a drawing. Then, to get your matches you create a query that has that tblNumbers in it 2 times. You link them via ID_Drawing and num_Value, bring down the num_Type fields from both tables, put "Played" in the criteria for one of them and "Winner" under the other. That will tell you what numbers matched between your chosens and the actual winners.
