Confiforms - How can I update a value in all records that have a specific value in another field?

[Chris_Stewart]

I have a form that has group IDs (text field), called classes,  that is defined by various other fields. 

When I update a record, I would like all of the records matching that group ID to update a field called "seats" with the value of the modified record.

I've tried a number of variations using IFTTT(Create/Update Confiforms Entries) without any luck. Any advice is welcome.

~Thanks

The answer was much more simple that I thought. I needed to use IFTTT (update confiforms entries by filter) instead of (Create/Update Confiforms Entries).
