Showing list values as extra fields

Hi all -

I've been using extra fields in T3 for quite a while, using the method shown here.

However, I've now added a list to the extra fields and need to know how to show conditionals based on the value selected in that list. For example, if value 1 selected, then show this.

My XML:

  

          1

          2

          3

        

 

As you can see my code is only based on the conditional that any value is selected; help selecting the value appreciated!

Thanks
