Dragging multiple movieclips senocular - begindrag -

Hi I have a site that uses a custom cursor, I would also like to be able to drag other objects around. However in flash this seems to be quite difficult.

I came across this site called senocular and they had a .as file called [URL=“http://www.senocular.com/flash/actionscript/?file=ActionScript_1.0/Prototypes/MovieClip/beginDrag.as”]beginDrag.as

They had some simple useage for the script:

on(press){
this.beginDrag(true,0,0,300,300); // constrained to 300x300 square
}
on(release, releaseOutside){
this.endDrag();
}

however this did nothing. I have tried importing this using

import “beginDrag.as”;

and have even tried pasting it into the first frame of the movie. however none of this worked.

Could someone help me get this working.

Thanks
