Google-sheets – sum of specific lines

google sheets

How can you sum specific lines?

When I add up specific lines such as A10:B20:C30 I get the entire column which doubles the figures.
It is picking up the specific totals plus the individual columns

As Tedinoz and Rubén mentioned you mixed up the operator for ranges, which is the colon with the separator for a list, which is the semicolon. =SUM(A10;B20;D30) will work because it's a list of fields.
