Inserting a Function Into Array Declaration

[Bobby Smith]

Hi,

I am trying to use LOOKUP to find the last instance of a value in a list that will grow to an undefined length, this is the formula I'm using:

=LOOKUP(2,1/($C5:$C(last_row)=A1),$D5:$D(last_row))

last_row is a MATCH function (that works) that reads down until the first blank cell and returns the length of the list, this list could be 10 one day and 100 the next, it's impossible to know how long it is.

The problem with the LOOKUP function is here: $C5:$C(last_row) Excel doesn't seem to like that I use last_row in the array declaration even though it returns a number, is there a way to reconcile this?

Hi Bobby,

If you don't know how big your array will be, you can use a Dynamic Named Range for it.
