Finding non zero value in a group of cells

[Eric H]

I have a monthly list of Selling Prices by part that I want to use a formula
on to retrieve the most recent price. The problem occurs when the last
month(s) in the list has no sales and thus no sellng price. See Below:

Sep Oct Nov Dec

Part A 4 4 4 3
Part B 2 2

I can't use 12 If Statements to say "If Dec is 0, use Nov, If Nov is 0 use
Oct, etc". What formula can I use that will go backwards (In this case Dec
backwards) until it finds a value?

=LOOKUP(2,1/(28:28>0),28:28) will give the last value in row #28, for example

Assuming the cells are empty (as your sample portrays) and do not contain
numeric 0.

Try this:

=LOOKUP(1E100,B2:M2)
