I am trying to ad onto an IF formula and I need help. I am using this formula
to count the number of apartments that are vacant. Some apartments have
illegal tenants (squatters). The formula below counts how many are "vacant"
or have "squatters", where squatters replaces vacant.

The formula is: =COUNTIF(C2:C56,"Vacant")

Now I need to count how many 1, 2, and 3 bedroom apartments are either
vacant or have squatters. The D column shows either a 1 for 1 bedroom
apartment, 2 for a 2 bedroom apartment, or 3 for a 3 bedroom apartment.

I tried =COUNTIF(C2:C56,"Vacant",D2:D56) but it did not.

What am I doing wrong.

Thanks for any help out there
