Hey @Amjl 
You can’t access the inputs/elements inside a repeating group by clicking a button outside repeating group. You can only access using a button inside the repeating group. That makes sense mostly because the cells in a repeating group will change based on the data source of the repeating group.
If you want to create some bulk information from a repeating group inputs, you can check this guide: Dynamic row addition in Repeating Group and bulk CRUD of Things using vanilla Bubble
Or, if the inputs should not necessarily be inside a repeating group, move them out of the repeating group.
I hope these help.
