Hi,

If there are more than two occurances then you could use:

=IF(B2="","",IF(COUNTIF(C$2:C$9,C2)=COUNTIF(C$2:C2 ,C2),SUMIF(C$2:C2,C2,B$2:B2),""))

And if there are no blank rows you can shorten this to

=IF(COUNTIF(C$2:C$9,C2)=COUNTIF(C$2:C2,C2),SUMIF(C $2:C2,C2,B$2:B2),"")

Assuming titles in row 1

In D2:
=IF(C2="","",IF(LOOKUP(2,1/($C$2:$C$9=C2),ROW($C$2:$C$9)-1)=ROW()-1,SUMIF($C$2:$C$9,C2,$B$2:$B$9),""))

Copy down
Adjust your range to suit

I need to add data if sites match in one column (C). If they match, then
corresponding cell data from Column (B) are added together and as a sum in
Column D. If there is not a duplicate match it would be great if the cell
just carried over to Column D. The duplicates are not consistent and single
sites are intermixed. Column B is numeric, Column C is text

Example

B C D
1 s234 1

2 s235
5 s235 7
4 s236 4
5 s237
1 s237 6


Thank you for your input.
