Activating a movie when text is entered

Hi! This is my first time here.

I have an .swf file that is going to serve as a login for a new website being built. The .swf will contain a movie symbol and two text fields underneath it. The idea is for the movie symbol to play at different points on its timeline based on what is being typed in the text fields below. For instance, when someone is typing in their user name, the movie file will start at a certain point on the timeline and when they type in their password, it will jump to another point in the timeline. I figure thats the easy part and I would settle for just that.

The complicated part is this: Ultimately, I want the movie symbol to jump to those points on its timeline based on how many characters have been typed into the text fields. For example, if someones user name is “christoper”, I need the file to play the movie once someone has typed in “chri” and then jump to the next section of its timeline after they’ve typed in “stopher”, and so on down through the password.

Can this be done?
