Average Of Numbers Between If They Fall Between Dates

I have to columns of data

Date and number

4/1/2012861,808
11/1/2011594,930
11/1/20102,740,320
11/1/20121,041,948
10/1/20111,726,000
10/1/20091,628,000
10/1/20082,059,929
10/1/2011 4,002,000
9/1/20062,979,602
9/1/20073,774,000
9/1/2011NA#

I want to take the average of the numbers between if they fall between dates of 2006 and 2007.

I can not do it with averageifs because I have that NA# in the second column. I dont know what to do.

I have something that works but only if it does not contain NA#, below is the example of what works:

=AVERAGEIFS($D$2:$D$131,$B$2:$B$131,""&H2)
