Is there an easy way to Sum from a Column within a Logical Operator?
Two Columns. First Either says "Vacant" or says the name of the tenant.
Second is the Rent Amount. The Logical Operator is IF (B4<"Vacant",D4,0).
But I want to add up the entire column (when Operator is true) within the
function. The only way I can think to do it is:

=IF(B4<"Vacant",D4,0)+IF(B5<"Vacant",D5,0)+IF(B6 <"Vacant",D6,0) and so
forth down the column.

At the end the cell should hold the total non-vacant rents for the complex.

Any ideas?

Thanks,

Casey
