Hi,

This finds the 'last' value 0 in the range

=LOOKUP(2,1/(A1:L10),A1:L1)

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

Hi,

I have lots of rows of data which are either a value between 50 and 200 (e.g
115) or "0".

Each column is a specific week of the year, ie from 1/1998 to 52/2009, so
the values run from left to right giving a number for each week, and when
there is not an entry for that week, there is a "0".

I need a formula to find the last number entry of each row. I could
obviously do this by scrolling to the last week (52/2009) an looking back
until I see the first number which isn't 0, however I need to do this for
around 1600 rows of data.

I would greatly appreciated it if anybody could help me with this quiery.

Thanks for your time.
