Hello,
I attached pictures to help ask my question.
I have a Geodatabase, and I created a Domain. I did right click->Properties and chose the "Domains" tab. The domain I created is a Coded Value, and I chose Text for the Field Type. I was able to easily type in the information within the Geodatabase, but I cannot do anything within the Feature Class.

I then did right click->Properties and chose the "Fields" tab for the feature within the Geodatabase. Within this tab, I cannot select anything such as adding in a new Field Name or selecting a domain. I also cannot update the current field names to choose a current domain. I completed a tutorial yesterday, and I was able to do that with their data. I would like to try to create a new Field Name, but I cannot even type there to add it in.

Does anyone know what is going on, and what I can do to fix it? Thank you!
