Problem with attachMovie and scrollBar

programming flash
1

I am trying to attach the scrollBar component that ships with F7/+. I can use this
ActionScript Code:
[FONT=Courier New][LEFT][COLOR=#0000ff]this[/COLOR].[COLOR=#0000ff]attachMovie[/COLOR]COLOR=#000000[/COLOR];
[/LEFT]
[/FONT]

and that works fine. However, if I do the below script it doesn’t work. Why?

 ActionScript Code:
 [FONT=Courier New][LEFT][COLOR=#000000]**function**[/COLOR] initializeElements[COLOR=#000000]([/COLOR]g[COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]

Everything works fine, except the attaching of the scrollBar. Like I said, it works if i just do the this but when i use target_mc it doesn’t work.
