How can I use methods of a MovieClip that is inside a ScrollPane?

I'm using a movieClip inside a ScrollPane to show a list of CheckBoxes. The amount of CheckBoxes shown is dynamic, it depends on a SQL query. After the query is done, I add as many CheckBoxes as rows in the result set.

What I am trying to do is to access some methods I wrote in the MovieClip inside the ScrollPane to get the length of the CheckBoxes, check which ones are selected and the label they have (their label is also defined by the SQL query).

I've tried this

valueINeedToGet = Object(root).scrollPaneInstance.source.functionINeedToRun();

but it returns error #开发者_运维知识库1006

Any idea how can I access the code inside the MovieClip inside the ScrollPane?

Thanks!

That error is because you aren't calling your method on a particular instance of your class that extends Movieclip. Also, making the root an object type will make it into a type that isn't going to implement the function you wrote (obviously) so that call to Object(root) will always fail.

Access the scrollpane by instance name--Then :

Access the children of the Scrollpane, cast them to the class you need them to be, then call the method you need on each one.
