XML based drag and drop

Question

ok, im not new to any of this really. Im simply stuck and
cant figure out why my drop targets arent working. my variables are
tracing directly before the drop target is evaluating.... its just
not returning that it is droped on the target.
the specific problem:
btn.onRelease = function(){
stopDrag();
target_ = _root["t_"+ a_num];
droper = _root["d_"+ a_num];
trace(droper + "//" + target_);
//////--------------------THE
PROBLEM--------------------///////
if (eval(droper._droptarget) == target_) {
trace("Success");
}else{
trace("failure")
here is the code in full:
//sets animation begin point variables
for(i = 0;i< 10; i++){
tx = i*125;
ty = i*125;
dx = 180;
dy = i*125;
//loading animations and non-xml text loads//
obs_box.top_.tex_1 = "Drag and Drop Exercise";
obs_box.stg_.slideTo(obs_box.stg_._x, -467.5, 1,
"easeOutQuad");
obs_box.top_.slideTo(obs_box.top_._x, -525, .75,
"easeInOutQuad", .25);
side_bg.slideTo(side_bg._x, 175, 1, "easeOutQuad");
//load xml//
var terms_xml = new XML();
terms_xml.ignoreWhite = true;
terms_xml.onLoad = function(success){
//end loading of data//
if (success){
var main_ob:Array = new Array();

//attaches the drop target movie clip (t_1) and created text
fields//
amount = main_trgt.length;
for(x=0;x<amount;x++){
ypos = x*25;
_root.attachMovie("target_", "t_"+x,x,{_x:tx, _y:ypos});

Answer 1

this & droper both return the same object. i actually
have it back to this right now. the one i posted up was just
testing. ive run out of ideas so im testing the stupid things.
sooooo, anyone else got ideas on why it isnt reading when the
object is dropped?
