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.

If desired, send your file to my address below. I will only look if:
1. You send a copy of this message on an inserted sheet
2. You give me the newsgroup and the subject line
3. You send a clear explanation of what you want
4. You send before/after examples and expected results.

You could use this array* formula:

=INDEX(2:2,MAX(IF(B2:Z2<0,COLUMN(B2:Z2))))

Copy down as needed
*Array formulas must be confirmed using Ctrl+Shift+Enter, not just Enter.

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,
assuming first row in 2 and formala below in column A, try this formula.....
=OFFSET(B2,0,COUNT(B2:L2)-1)

Adjust cell references to suit your data.

This will return the rightmost numeric value that is not 0 from the
referenced range:

=LOOKUP(1E100,1/B2:Z2,B2:Z2)
