Hi Bernie,

It's magnolia again. I forget to mention it but I tried in you formula
=IF(K4="Initiale";INDEX($L5:L$97;MATCH("Initiale"; $K5:K$97;FALSE))-L4;"")
to win a column and base the formula only on the presence or absence of a
date/time in column L. With the same amount of success than previously. There
are many empty cells between two cells containing a date/time. Tried to
replace "Initiale" with "ISNUM", NOTISEMPTY, etc...nothing doing.

In C1, something like:

=IF(A1="Start",INDEX(B2:B1000,MATCH("Start",A2:A10 00,FALSE))-B1,IF(A1="Fill"
,INDEX(B2:B1000,MATCH("React",A2:A1000,FALSE))-B1,""))

If you post a sample data set, tih your desired results, we'll be able to do
better.

Good evening everyone,

On this forum I've been given (3/29/2005, Bernie Deitrick) formulas to
calculate time differences in column C base on the word "start" in column
A
and Date +time in column B. "Start" appears from time to time. Now, I need
this time difference not only when the word "start" appears but each time
the
word changes in column A. Words in column A a start, fill, react, and
others. "fill" for example may appear several times before the word react
appears. I need the time spent between start and fill, between fill and
react
and so on. All my trials failed to adapt the formulas.
Else, is there a way to adapt following formula for DIFFERENCE instead of
SUM?
in column B =IF(A1="";"";SUM.IF($A$1:$A1;A1;$B$1:B1)). numbers in B have
the
form [HH]:MM.
And a other question:
each time that in a row the word "Start" appears in column A with
date+time
in column B,and batch number in column C, I want this date+time and batch
number be sent to a row located on a other worksheet but same file. The
next
row with "Start" etc.. may be 10 rows underneath the previous. How can I
do
it?
Thank you for any suggestion
