Hi, I made a saved search that looks like this ↓ I want to add a sum of each grouped field.. For example, Sum of John, Sum of Jesse... Is it possible in a saved search?? Or should I use a report?

Yes its possible. https://blog.prolecto.com/2015/05/26/solving-the-netsuite-cumulative-saved-search-tally-challenge/

@sam1128 Thanks, I tried the link above, doesn't seem to work when I set the SUM field as group .... What could I've done wrong?

You can by saved search to group your name and sum the amount But you need to click on the name to see the details
