Thank you Tom. I have put this in as a module. I am not sure how I use it
though. Do I need to write =check_for_dups(???????) and in what cell do I
put
this in? Thanks for all your help.

sub check_for_dups()
Dim lastrow as Long, i as Long, j as Long
Columns(3).Interior.ColorIndex = xlNone
columns(5).Interior.ColorIndex = xlNone
lastrow = cells(rows.count,"C").end(xlup).row
for i = 2 to lastrow - 1
for j = i + 1 to lastrow
if cells(i,"C") = cells(j,"C") then
if cells(i,"E") = cells(j,"E") then
cells(i,"C").Interior.ColorIndex = 3
cells(j,"C").Interior.ColorIndex = 3
cells(i,"E").Interior.ColorIndex = 3
cells(j,"E").Interior.ColorIndex = 3
end if
end if
Next j
Next i
End sub

No figure in column C will ever appear in column E and visa versa. It
is just
a case of looking for where any name in C and name in E appears more
than
once. Duplicates of any name in C does not matter. It only matters if
it has
the same name in E in both rows. Thanks

Would the duplication of E2 have to be in column E or could (for
example)

C9 = E2 and E9 = C2?

would any matches/duplicates be marked in both locations (rows. 2 and
9 in
the example) or would the first occurance be unmarked.

This is then searching for whatever is in E1 in column C. I want,
if C2 and
E2 repeat further down in say C12 and E12, it would highlight this
somehow.
Thanks

something along the lines of
in: I1
=(countif($c:$c,$e1)+countif($e:$e,$c1))2

then drag fill downt he column.

This is excellent but I am only looking to do pairs at a time,
such as column
c/e or e/f, not the whole lot at once, any ideas? Thanks

In the 9th column put a formula like

=SUM(COUNTIF($A:$H,$A1:$H1))8
entered with Ctrl+Shift+Enter rather than just enter since
this is an array
formula.
This is for I1
No select I1 and drag fill down the column

Rows that have values that are found anywhere in another row
will show true.
This assumes every cell contains names of interest.

Hi
I am hoping someone can help me. I am about to fill a
spreadsheet with data
and i have a problem. There will be about 8 columns but
what i need to do is
highlight where there are multiple pairs of data. Not if
say column 5 has
multiple names but where column 5 has a name and column 8
has a name. I need
to highlight any rows there the same two names occur in
these cells. I would
like this to search automatically as there will be
thousands of names. I need
to be able to do it comparing columns 5-6, 5-7, 5-8, 6-7,
6-8 and 7-8 but I
assume I just copy the same formula accross. Can anyone
help me please. Thanks
