I need to sum only those cells in column "C" opposite which are cells on the left that contain the word "Russia". In the document that I attached, when at least one "Russia" is found, all the cells of the "C" column are summed up at once.

Answer 1

=SUMIF(B3:B9;"Russia*";C3:C9)
if Excel is "Russian", then it will be SUMIF instead of SUMIF.
