Using multiple columns on Advanced Filter

[osprey35]

I've set up an advanced filter that will filter rows that have a Y in columns J and K. But I only want those rows to be filtered if column N is blank. I can't do this and being very blonde.
Thanks for any help whatsoever

Highlight columns J, K, and N
filter
click on the filter button on J, make sure that only "Y" is checked,
do the same for Column K
click on the filter button for N, make sure only "BLANKS" is checked

Let me know how it goes.
