Hi!
Need help!

I have 114 drag movie clips (one on other, overlapping movie) on the same frame. By clicking a button (on the same frame) 7 movie clips (randomize) should be visible and active to drag. Those movies that are in front are active and I can drag them, the other are visible but can not be drawn. I have used the function swapDepths(20) but it doesn’t help me.
Here is my button script:

Code:
on (release) {
	_root.gift._visible=false;
	stopAllSounds();	
// with drop I mean drag.
drop1._visible = false;
drop2._visible = false;
drop3._visible = false;
drop4._visible = false;
//------//----------
drop113._visible = false;
drop114._visible = false;

var rndnum1 = Math.floor(Math.random() * 114) + 1;
var rndnum2 = Math.floor(Math.random() * 114) + 1;
var rndnum3 = Math.floor(Math.random() * 114) + 1;
var rndnum4 = Math.floor(Math.random() * 114) + 1;
var rndnum5 = Math.floor(Math.random() * 114) + 1;
var rndnum6 = Math.floor(Math.random() * 114) + 1;
var rndnum7 = Math.floor(Math.random() * 114) + 1;

var tong1 = this["drop" + rndnum1];
var tong2 = this["drop" + rndnum2];
var tong3 = this["drop" + rndnum3];
var tong4 = this["drop" + rndnum4];
var tong5 = this["drop" + rndnum5];
var tong6 = this["drop" + rndnum6];
var tong7 = this["drop" + rndnum7];

tong1._visible = true;
tong2._visible = true;
tong3._visible = true;
tong4._visible = true;
tong5._visible = true;
tong6._visible = true;

//_root.swapDepths(tong);
//this.tong1.swapDepths(20);
 
}
