Am I confused or is the UIBuilder?

[Galn]

I just started playing with the UIBuilder and read the tutorial that was posted (doc file download) and it makes a lot of sense. I have been able to do some things but I REALLY want to make some changes on the create tradeskill window. Well I cant find the template for it, the initial screen is there but when I click on ok (with play on) it just blinks at me. Even if I click on things in the tree on the left it doesnt work.

As the title says, am I confused and there is no template for that window or is it hiding on me?
