Hi @andrew-fleming
Please try to post code in code-tags so it’s easier to read, copy etc 🙂
There’s a few things you can check here. For starters, make sure that your selector is correct
#acf-field_55c1f48f145b8-55dec8c84845f-field_55c1f4bd145b9
I think that all subfield have their own specific IDs so you might have to rethink how you target them. Also, do a console.log($el)
to see wether the element you’re in actually has the select field as a descendant.
