Please help me!!

I am using this function/formulae:

=COUNTIF('Test Schedule'!V:V,B3)

This function counts every value equal to cell B3 appearing in the 'Test Schedule' tab in column V.

However, I want to added another variable – I don’t want to count all of these values - I want to exclude those entries where the value in 'Test Schedule' tab where column K equals “N” … that way, I only count the value where column "K" only reports on the value “Y”.
