So, `ring_numbers’ is a filed on the user profile page. It appears to be returning an array, or at least you think is should be. What type of a field is this?
Then….
What would be easier is if you export the two field groups that the fields ring_numbers and leg_ring_number are in. Not sure what version of ACF you’re using, but if you can create a file an put it in a .zip arcive you can attach it here (paperclip icon to the left of the message field). That would probably give me a better idea what you’re working with than trying to explain it.
