Excel IF 函数同时跨多行和多列

Question

I manage a student housing apartment building and have my rent roll within a excel document. In my property, residents are able to lease at multiple rent levels (whole unit, room within unit, or bed within the room). I am looking to be able count the number of "Vacant" rooms if both of the beds within the room are labeled "Vacant".

Column C has the unit number

Column D has the room number

Column E has the bed number

Column F has the resident's name

Unit 923(C1) room1(D1) Top(E1) John Doe(F1) Bottom(E2) Vacant(F2) room2(D3) Top(E3) Vacant(F3) Bottom(E4) Vacant(F4)

In this case, unit 923 is a two bedroom unit with four beds (two in each room). Room 1 is partially occupied by John Doe and is therefore not available at the room level. Room 2 has both of the beds "Vacant", so it is available to be rented out at the room level.

Thanks in advance!

Answer 1

You can nest logic with AND and OR to figure it out:

IF x AND y => true if both x and y are true

IF x OR y => true if either x or y are true

IF x AND (y OR z) => true if x is true and either y OR z is true

See here for some examples. Here is a more formal explanation

Answer 2

I added an additional column G to contain the results of the IF function. My final formula is:

=IF(AND(AND(F3="VACANT"),AND(F4="VACANT",AND(D4=""))),1,0)

I just add the new column's values for the number of available bedrooms.
