Luis,

If the values are contiguous, then the simplest to use and understand would
be

=MATCH(A9,$A$41:$A$10000,0)+COUNTIF($A$40:$A$10000 ,A9)+39

If they are not contiguous, then array enter (enter using Ctrl-Shift-Enter)

=MAX(($A$40:$A$10000=A9)*ROW($A$40:$A$10000))

I have blocks of data in a sheet, every time there is an entry in column A
a
new range begins and (in terms of rows) goes as far as until there is
another
entry in Column A.

All the entries in Column A are in A9 with "validation data list" i need
to
retireve the last row of the range of the selected entry using built in
formulas.

I have this to get the first row and it works
=MATCH( A9,$A$41:$A$10000,0)+40

Need the one to find the last row of that range which is delimited by the
next entry in ColA
Thanks in advance
