Textfield problem

Hi,
wth this tut. http://www.emanueleferonato.com/2008/11/11/as3-flash-game-creation-tutorial-part-4-score/

Ive used to code to add a score… but i got the error “1119: Access of possibly undefined property Scoretext through a reference with static type Score.”

Now ive looked at the library of his fla (the rar is on the buttom of the tut page)
And there is a score on the library…

Now is it possible to get the same effect withouth having anything (like a textfield) on the library?

So, can you make the textfield by just using as3…
