You could click on adding an Admin Fields and we are going to use the name and join that up with the email and with the web URL. We will see that there is this 'Area' column. The Area column can target three places, before modeling the value, after modelling the value, and the view.

Whereas in the view you must think of already having an HTML trunk that represents that field.

We are going to make multiple changes and show you what will happen. Save you some time, and understand what's happening. The first area I'm going to target is the model area. Then it has a Joint Type which is either a concatenation with a 'Glue' option. The 'Glue' option is: what do you want to be placed between the values? You could say no I want them to be completely crank up against each other like that (Glue/Code). It will still add a little space in.

It is a value you want to place between these two values. I'm going to leave it as a comma for now. Save and close. Save and close the view.

Because it's exceeding a specific length, it is escaping it and we have this little Pop-up come up. There is that comma we added as a concatenation between the values.

Another thing. You can only target the name list field once. You cannot add it a second time like this(see video) and say here we are going to do it again. Using maybe some other values to also target it in some way. [00:13:52](https://www.youtube.com/watch?v=hh4IIPmYIY8&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h13m52s) You cannot do that. Only one of them will get implemented. The other one will be dropped. It's a limitation I know. Believe me this feature as it is now is already stunning and able to achieve quite impressive results. Here we have it, we have adapted it. It will only show an email or a web address if there is one set. If there is none set, it will not show any. That is the expected result.
