What are Roll-Up Summary Fields in Salesforce?

I was trying to create same rollup summary on account but i don't see amount in field to aggregate option. Please help

Really enjoyed the way you explained the concept of rollup summary! Thank you for making great videos!

just thank you so much for this content

Best explanation of a rolllup summary! Thank you!

Thank you for this video! Trailhead is horrible at explaining why we are doing these modules. Now I understand what rollup summary is and what it can really do! It's hard to study with trailhead when at the end of the module they don't show you what you did and expect you to understand what you're doing.

thanks 4 valuable inforamation about roll up summary......please continue series.👌✌🙏

So Informative but I wish I could find also about validation Rules and Flows etc. Because your explanation is so clear. Thank you in Advance and wish you Best Luck!

Wow great Explanation,Thanks a lot.

Explained this like a pro. I did this on trailhead and was baffled as to why I was doing this. Thank you for your service sir.

Very informative video! Thank you
