im not using code on the index.fla for it i put a UI Loader and put the folderadress in the source blank in its properties,
i mean, i do have code in the index just not having anything to do with the UILoader or its source. the UI loader is in frame 1, wich i named "musicframe"
the only other action i have in that frame is on a layer above and its only a stop().
the code for the as file class "Volume" is
package

to the stage and centers them based on the height and
width of the stage. In addition, a rectangle object is
created to 'contain' the sliding circle, like an imaginary box.
We pass -100 as the x value because it is added relative
to our sprite. If we set its x value at 0, or the sprites default x
value,the boundary would stop and start at the slider sprite. Change
-100 to 0 in the rectangle object to get a better idea of its use.

this as file i use as "volumecontrol" 's class, wich is a blank fla. with only one blank frame. by itself it works perfect :S
and this is everything that shows on the output panel, after debugin permited is checked:
" TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Volume() "
please, enlighten me x_x
