Excel/Finding the last >0 entry in a row

Question
Hi Tom,

Scoured everywhere, but all I get for my results in AZ3 are zero!

I have a set of values working from C3 across to AZ3 - come back to that later...

C3 is a random generated number (as are C4 thru C51):
=randomnumbers(1,$A$1) - $A$1 being the number of teams in the competition

C3 = 14

D3 is also a random generated number, but if it is found more than once in C3:C51, the random number generator runs again (once):
  =IF(COUNTIFS(C$3:C$30,$C3)=1,C$3,randomnumbers(1,$A$1))

D3 = 14

All good so far, but now in E3, I have this formula:
=IF($C3=D3,"",IF(COUNTIFS(D$3:D$30,$C3)=1,D$3,randomnumbers(1,$A$1)))

All this means is that E3 returns "".  That's great cos copying the formula across to AY3 also returns "" in each cell.

What I want to do is lookup the last value, looking from left to right, in C3:AY3 and return it to AZ3.  In this example the answer should be the contents of D3, ergo 14

Can you help with the correct syntax for Cell AZ3 please mate?

many thanks in anticipation

Pete

Answer
Pete,

Try this formula in AZ3

=LOOKUP(10000,C3:AY3)

just make the 10000 any number bigger than a value that will appear in C3:AY3.  If the numbers will be less than 10000, then just leave it as 10000.  This should return the value of the last cell in C3:AY3 that has a number.  

This would return 0 if it was the value of the last cell with a number.  If you really want to exclude zero cells, then you could use this formula

=LOOKUP(10000,IF(ISNUMBER(C3:AY3)*(C3:AY3>0),C3:AY3,""))

this should be entered with Ctrl+shift+enter since it is an array formula.
