[AccessD] ...gurus only

Hi William

1) No problem.

2) Sorry, now I understand.
  Use this for Series:

      IIf([First]+[Last]=0,
        0,
        1+[Last]-[First]) AS 
    Series

3) If you expect "" for empty fields, values must be strings. That's why I use Val() to convert to Integers.

...thanks gustav but:
...I'm busted again ...there was an error in the data3 max ...sigh
...given:

fields        w        x        y        z        max        series
data1        1        1                            1             2
data2        1                  5                  5             3
data3        1        4                  3        4             4
data4                  2        3                  3             2
data5        1        1        1        1        1             4
data6                  1                            1             1

1) where max is the largest number in w/x/y/z and
2) where series is the total number of fields between the first one 
containing a
number and the last containing a number, not the total of the field 
contents.
3) where w/x/y/z are long integers for some stupid reason since it will 
allways be a single digit

...I ask for guru help and everyone starts exposing why I need it :(
...there is a desperate shortage of caffiene in my bloodstream ...that's my 
story and I'm sticking to it :)
