I am trying to add an ISRC column and go to add ISRC through the Extended Tags drop down. As you can see from the attached image when I choose to add it the "Okay" button is not functional.
Help?

Could it be that you have to enter some content (in the box below ISRC) first?
The reason:
You can not add new "empty" fields.
The fields exists either WITH content or they don't exist at all.

You need to include a value there before the OK button will be active.
If you simply want to create a new column without setting a value first, use the View\>Customize Columns method instead. You can create as many new columns there as you wish, and assign which tag values or functions you want.

These are two different things:
a) Columns (visible in the Excel style table called "File List")
b) [Extended Tags](https://docs.mp3tag.de/extended-tags/) (showing the content of every selected track)
What exactly do you want to add?
A new [column](https://docs.mp3tag.de/customization/file-list/) or a new ISRC field in the track?

Hi! A new ISRC field in the track.

It gives me the ISRC option under Extended Tags but won't let me "OK".

Okay. I get what you were saying. So I added the ISRC code for the song in question and the "OK" became functional. I don't see it in the file listing, though. When I hit Command T it's there. But I'd feel better if I could see it in the file listing as well.

Then just follow the already linked instructions to add a new (ISRC) column:
> **[File List – Mp3tag Documentation](https://docs.mp3tag.de/customization/file-list/)**
>
> Customization options for the File List, including adding, removing, hiding, and rearranging of columns. Mp3tag is the universal Tag Editor.
BTW:
If you use a Mac you can read the instructions here:
> [@Customization of Tag Panel and File List](https://community.mp3tag.de/t/customization-of-tag-panel-and-file-list/56067#customizing-the-file-list-2):
>
> Mp3tag supports flexible tagging, which means that the tag fields available on the Tag Panel on the left and as columns in the File List are not fixed. While you can reference any field which is, e.g., listed in the extended tag dialog as name via a placeholder %name% in Mp3tag, it's also possible to customize the UI using these placeholders. Customizing the Tag Panel The Tag Panel is the sidebar on the left of the File List that shows the fields to enter metadata. Besides the standard field…
