I am in a for loop creating clips and assigning a rollover script to each. It works if I hard code gallery\_mc1.enterFrame = navGrow; I have pasted the relevant parts of the script below.
```
this["gallery_mc"+i].onRollOver = function() {
this["gallery_mc"+i].enterFrame = navGrow();
};
```
//////////////////////////////////////
navGrow = function () {
if (this.\_xscale\<100) {
trace(“it triggered navGrow”);
this.\_yscale = this.\_xscale += 5;
this.\_y -= 5;
this.\_x -= 5;
} else {
this.onEnterFrame = null;
}
};

That code looks fine, post the rest of the loop. I usually use a variable to refer to the movieclip for events like this.
Edit: wait… what is enterFrame, shouldn’t that be “onEnterFrame”?

Here is the rest. When you talk about assigning a variable you mean something like this?
temp\_mc = this[“gallery\_mc”+i];
///////////////////////
import flash.display.BitmapData;
import mx.transitions.Tween;
import mx.transitions.easing.\*;
var offset = 0;
for (i=1; i\<5; i++) {
// Create imageBmp and attach the bitmap from the library.
//var imageBmp:BitmapData = BitmapData.loadBitmap(“image”+i);
// create movie clip and attach imageBmp
this.createEmptyMovieClip(“gallery\_mc”+i, i);
this[“gallery\_mc”+i].loadMovie(“images/gallery”+i+".swf");
this[“gallery\_mc”+i].\_xscale = this[“gallery\_mc”+i].\_yscale=70;
this[“gallery\_mc”+i].\_y = 100;
this[“gallery\_mc”+i].\_x = offset += 3;
offset += 170;//this[“gallery\_mc”+i].\_width;
trace("offset = " +offset);
trace("gallery\_mci = "+this[“gallery\_mc”+i]);
trace("gallery\_mci.\_width = "+this[“gallery\_mc”+i].\_width);
//////////////////////////////////
this[“gallery\_mc”+i].onRollOver = function() {
this[“gallery\_mc”+i].enterFrame = navGrow();
};
//////////////////////////////////
this[“gallery\_mc”+i].onRollOut = function() {
this[“gallery\_mc”+i].enterFrame = navShrink();
};
}
this.stop();
///////////////////////////////////////////////
navGrow = function () {
if (this.\_xscale\<100) {
trace(“it triggered navGrow”);
this.\_yscale = this.\_xscale += 5;
this.\_y -= 5;
this.\_x -= 5;
} else {
this.onEnterFrame = null;
}
};
////////////////////////////////////
navShrink = function () {
if (this.\_yscale\>70) {
this.\_xscale = this.\_yscale -= 5;
this.\_y += 5;
this.\_x += 5;
} else {
this.onEnterFrame = null;
}
};

No, more like this:
```auto
import flash.display.BitmapData;
import mx.transitions.Tween;
import mx.transitions.easing.*;
var offset = 0;
for (i=1; i<5; i++) {
// Create imageBmp and attach the bitmap from the library.
//var imageBmp:BitmapData = BitmapData.loadBitmap("image"+i);
// create movie clip and attach imageBmp
var gallmc:MovieClip = this.createEmptyMovieClip("gallery_mc"+i, i);
gallmc.loadMovie("images/gallery"+i+".swf");
gallmc._xscale = gallmc._yscale=70;
gallmc._y = 100;
gallmc._x = offset += 3;
offset += 170;//this._width;
trace("offset = " +offset);
trace("gallery_mci = "+this);
trace("gallery_mci._width = "+this._width);
//////////////////////////////////
gallmc.onRollOver = function() {
this.onEnterFrame = navGrow();
};
//////////////////////////////////
gallmc.onRollOut = function() {
this.onEnterFrame = navShrink();
};
}
this.stop();
///////////////////////////////////////////////
navGrow = function () {
if (this._xscale<100) {
trace("it triggered navGrow");
this._yscale = this._xscale += 5;
this._y -= 5;
this._x -= 5;
} else {
this.onEnterFrame = null;
}
};
////////////////////////////////////
navShrink = function () {
if (this._yscale>70) {
this._xscale = this._yscale -= 5;
this._y += 5;
this._x += 5;
} else {
this.onEnterFrame = null;
}
};
//////////////

I switched the whole thing so that it is using a temp variable and it still doesn’t work.
this.createEmptyMovieClip(“gallery\_mc”+i, i);
temp\_mc = this[“gallery\_mc”+i];

I tried your method, but I can’t get it to work. I don’t know what to do… I am going to try messing around with a blank clip and duplicateMovieClip. That isn’t working either. UGH!!!
