Hi @Valkrider and all other readers.
Please do NOT select a custom field which looks like ‘field_123gh44f’. This is the field_name used to save the field object, not the field value.
All ACF values are saved using the field_name, so if you have created a field in ACF called ‘City’ with a field name of ‘city’, please select ‘city’ from the GF drop down list.
Thanks
E
