Please edit your question (Actions>Edit), select your code and press the button [CODE], which makes the code appear colored/indented, it'll be easier for people to look at it. Thanks!

That's quite a meaningless title!

A better title could be: "Change fields in selection screen when user selects other value in listbox"
