Unable To Customize Web Interface Form With "C", "CO", and "Country Code" Attributes
説明
When trying to add the "C", "CO" or "Country Code" Attributes to a custom Web Interface Form the Attributes are not available in the list.
対策
This is by design if the Custom Command "Country/Region" is already on the Web Interface Form. The "Country/Region" Command combines all three ("C","CO", and "Country Code") together and when modified updates all 3 Attributes. If you remove "Country/Region" from the custom Web Form then you'll be able to add the 3 Attributes separately.
