Compare numbers in 2 rows and give me a number how many numbers match?

[JSolitude]

Hello everybody,

I'm pounding my head on the following problem.

Suppose I have a sequence of 7 random numbers in a row, each number in the next column.
(I do know how to randomly generate numbers so this is not the problem).

On the next row I have another sequence of 7 random numbers.

For instance:

1 - 12 - 24 - 31 - 37 - 44
3 - 15 - 27 - 37 - 43 - 45

I'm looking for a formula that would give me as a result 1, because in this case when compared row 1 with row 2, the number 37 was generated twice.

If there would be 2 numbers that would be the same, the formula should give as a result 2, and so on.

I'm thinking about the formula 'compare' or 'search' but how do I construct the formula for the above problem

Thanks a bunch in advance.

One way (Note this is an array formula - confirm with ctrl+shift+enter):
Sheet10

*	A	B	C	D	E	F	G	H
1	1	12	24	31	37	44	*	*
2	3	15	27	37	43	45	*	1

<colgroup><col style="font-weight:bold; width:30px; "><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"><col style="width:64px;"></colgroup><tbody>

Thank you very much JoeMo. Very nice solution to the problem at hand -why did I not think of this, I'm simply lousy at Excel
