Simple expression conversion required.

Branch	OpeningDate	Closing Date
A	15-10-12 00:00:00	NULL
B	01-01-08 00:00:00	04:03:11 00:00:00

I have above criteria in database, with Branch A as open still, and Branch B closed.

In the Qlikview, user can select Year and Month from listbox. He can choose multiple Years or Months from listbox.

I am showing data in Pivot table, like below:

Now here, I want to show only those Branch(s) for which below criteria satisfies:

if (OpeningDate is less than Year and Month) and (ClosingDate is greater than (Year and Month or NULL))
then

it should show me Branch

else

it should not show

Can anyone translate it to expressions? Thanks in advance.
