[COLOR=#003366]above is the link to my files, and the actionscript is on the first layer of the root timeline, in the actions window you will find the following chunk of code halfway down in the middle. [/COLOR]
[COLOR=#003366]it uses loadMovie to load an external PNG from an Array (four images are included) but it wont let me change an of its properties, such as _x, _ height, and so forth.[/COLOR]
[COLOR=#003366][/COLOR]
[COLOR=#003366]this should be a simple challenge for an adept programmer but I know that something is worng with my syntax.

Please help. [/COLOR]

// ****
// ******************
// Trouble Spot : the loadMovie command successfully loads png file, but properties such as _height, and _x position below it have no effect on the loaded image file.
// ******************
// ****
//
_root.windowHolder.loadMovie(imagePlaceHolder[this.id], imagePlaceHolder[this.id], this.id);
//above the the Array imagePlaceHolder takes the values from the Array PortfolioArray (declared at the top) and imports those respective PNG’s
//But, below it wont change the properties of these image files such as their height or x position. - here is my question how do i get the following code to work?
_root.windowHolder.imagePlaceHolder[this.id]._height = _root.windowHolder.window._height1.1;
_root.windowHolder.imagePlaceHolder[this.id]._width = _root.windowHolder.window._width
1.1;
_root.windowHolder.imagePlaceHolder[this.id]._x = 0;
_root.windowHolder.imagePlaceHolder[this.id]._y = 0;
_root.windowHolder.imagePlaceHolder[this.id]._alpha = 20;
_root.windowHolder.imagePlaceHolder[this.id].setMask(_root.windowHolder.window);
