Trouble finding _droptarget with a swf!

Hi all,
I am having trouble in finding target in a drag drop scenario. I have a movie placeholder named onepic1 and i load a movie using


onepic1.loadMovie(this.img1lnk);

I load the img1lnk variable externally using

img1lnk=onepic1.swf

The SWF loads into the placeholder, NO PROBLEM in that!

And I identify a dragged object into that movie using

if (_droptarget eq "/onepic1") {...}

The problem is that it istnt going inside the IF logic. Previously i had

img1lnk=1pic1.jpg

and it worked. But when i replaced it with a .swf, it istnt working.

Am i missing something??
Replies appreciated!
