Button state onLoad?

OK, so I have a quite normal button named ‘Home’.
When the swf loads I’d like this button to be at the ‘Down’ state (aka: selected).

In an actions layer on frame 1 I have this:

onLoad.home_btn.gotoAndStop("down");

While the button does work, it does not start out selected. The button instance is named home_btn.

Does anyone have a suggestion please?
