First, sorry for my bad English. I am not fluent and I use google translate.
When clicking on a listviewer item (already connected with airtable) I need to go to another column of the same line selected (because it is the person’s current training, I’m a personal trainer)
the app shared will show you how to get an item from a different column in the same row as the item you click. also how to add items to the list. delete them. modify
