Automatically update number by one

H
Forum|alt.badge.img+1

Hi, 

I recently inherited the database for a club and I am trying to make the interface easier to use by creating an Airtable/Softr design instead of the manual version that existed previously.

Basically I have one table with member details that includes a field for number of events attended. I then have another table for events with a field called Attendees which lists all the Attendees of that event by pulling the names from the Member table. 

So, what I want to do is automatically increase the number of events attended field in the Members table by one if the member appears in the Attendees field in the Events table - how can I do this?

Possibly slightly complicating the issue is that since I have inherited this and am not starting from scratch, numbers of events attended figures already exist, so I am not starting from zero but from different numbers for each member.

Thanks in advance for all help!!

So each Member record has one or more Attendee record, each representing the events they've attended? It sounds like you could just add a Count-type field to the Members table rather than a manually entered Number -type field.

Would that work if I'm not starting from 0? Some of the members have already attended 50-100 events so I would need to start on a different number for each of them and then count on from there. Maybe with a formula? If I had number of previous events, then a count of the new events attended and then another column which uses a formula to add the two?

If you have a previous number, you can add each rows previous number to the count of the rollups to get the new number.

I don't see why not, go ahead and give that a try
