Drag and Drop Movie Clips in a particular sequence

[brebsy]

I need to create a 'match the component parts in the correct order' Flash movie, to be created using movie clips which drag and drop to their relevant outlines and which snap back if placed incorrectly.

Can someone provide me with the correct actionscript code to specify a correct sequence to the movie clips? i.e. if you try to insert portion B before portion A it snaps back.
I've been told I can do this by assigning a number to each movie clip and setting up a counter.
However, I'm fairly new to actionscript and this is beyond me!

I don't know if this helps or not.


b_dtss.onPress = function() {
this.startDrag();
};
b_dtss.onRelease = function() {
this.stopDrag();
if (this._droptarget == "/d_dtss") {
this._x = 251.5;
this._y = 219.5;
} else {
this._x = 65;
this._y = 62;

}
};
