Formula for not blank in one column and number in another column

[bbbb1234]

I want a formula that will look across the range below and tell me how many cells have a 1 in Col B but DO NOT have any text in Col A if Col B is 1. In the Data Range below, the formula result would be 1. I thought about something like this: COUNTIF(A2:B13,"AND(ISBLANK(A2:A13),A2:A13=1)") but this does not work however I think it conveys what I want.

Any ideas?

Data Range

Book1
	A	B
1	Col A	Col B
2	test1	1
3		1
4	test1	1
5		2
6	test3	2
7		3
8	test4	3
9		3
10		4
11	test5	4
12		4
13	test6	4

How about
=COUNTIFS(B:B,1,A:A,"")
