Getting SUM of related table column not working
Hi all, I'm trying to get the SUM of the values on a related table column, and although I'm not getting any errors, this doesn't work with my code. The two COUNT columns work, but the two SUM columns don't. Can someone point out what I'm doing wrong? Many thanks.
Solution
Found the documentation and
trips_sum_distance works! Thanks for pointing me in the right direction.
