Digital Workshop

I have been using opus for years and have written a few publications but have never got on with script. Even the easiest of functions I cannot get to work.
e.g I have declared a variable lets say its called billy. I add a script object to a button that reads, var billy = "silly" I have a text box that contains the variable billy but upon pressing the button silly is not displayed in the text box.
I know I am missing the obvious but, what is the obvious?
Any help would be appreciated.
