How to use a range in SUMIF?

I'm trying to find a month-to-date total for each of several years. I used
the following formula:
=SUMIF(B3:B350,AND(">="&K6,"<="&K2),L3:L350)
where B3:B350 are dates
K6 is the first of the month
K2 is Today
L3:L350 contain the amounts to total
The criteria give a "#Value!" error.

Any suggestions?
 
This works, but I'm not sure I understand why.

A short take on it ..
=SUMPRODUCT((B3:B350>=K6)*
Click to expand...
(B3:B350<=TODAY()),L3:L350)

The 2 condition tests:
B3:B350>=K6
B3:B350<=TODAY()

will evaluate into 2 arrays of TRUEs / FALSEs:
{TRUE,FALSE,TRUE, ...}
{FALSE,FALSE,TRUE, ...}

depending on whether:
B3 >=K6, B4 >=K6, ...
B3 <=TODAY(), B4 <=TODAY(), ...

Multiplying the 2 TRUE / FALSE arrays together would then evaluate to a
single numeric array of 1's and 0's:
{0,0,1, ...}

Corresponding items from array 1 are multiplied with those from array 2,
viz. for the sample above:

TRUE x FALSE = 0
FALSE x FALSE = 0
TRUE x TRUE = 1

and then .. SUMPRODUCT({0,0,1, ...},L3:L350)
would evaluate each as:
(0 x L3) + (0 x L4) + (1 x L5) + ...
giving the final required sum from within the range L3:L350

Thank you for your help
