Hey all, I have a summary table that shows these values. Each error log and log in the 'Total logs' column (which contains error logs and successful logs) have a unique timestamp. Process Error logs Total logs A 5 10 B 6 15 C 7 9     I want to find the total execution time for the error logs and the total logs for each process by adding the total execution times of the error/successful logs under each process. I am hoping to get a summary table like the one shown below. Process Error logs Total logs Total execution time A 5 10 2 minutes B 6 15 50 seconds C 7 9 4 minutes   Any help would be much appreciated. Thanks! ... View more
