I am building an app for an event using the Conference Template. There are different seminars with different availability. I want to build a functionality that counts “Favorites” for every user and event so people can RSVP and see how many people will be attending the seminars. I created a Rollup to count favorites but it sums it all up. Is there any way I can sum up only the favorites for a particular event? ![Screenshot 2022-09-20 3.13.16 PM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/0/a/0ab698b48f5a3e1f4f819620b5a99b92aabd28f5.png) Here is a link to the app [https://mallorcabjjyogafest.glideapp.io/](https://mallorcabjjyogafest.glideapp.io/) ---

There is no way to reliably sum a User Specific Column. One thing you could do is make a new table for each event , “Signed Up” which would simply have a RowID and a User ID. Then you could simply sum the records in that Table.
