Very easy button quesion and AS mode

Hey guys, not done any web design in AGES and can’t seem to remember how to do the simplest thing:

2 questions:

  1. I am trying to make a movie clip on the time line gotoAndStop at its 2nd frame when the mouse rolls over a button:
this.onRollOver {
	_root.ft1.gotoAndStop(2);
}

I am applying that script to the button.
ft1 in the instance name of the movie clip.

That tells me syntax in line 1, why?

When searching I saw a lot of people calling functions but I am pretty sure I never used them in the past to do just such a simple action.

  1. I seem to remember there was an actionscript “newbie” mode or something which helped ensure the syntax was right but I can’t remember how to access it.

This is MX 2004 Pro (old school) but I am doing something very simple.

Thx for any help.
