IDE :: Resize External Swf Movie To Stage Size?

What i try to do, is to make a "wrapper" in Flash, in which other swfs could be embedded. (passing the URL of the external SWF by URL) to attach a link to the swfs. (ClickTag - Issue, maybe someone knows this).In the HTML - Code this would look like this:

Code:
<embed src="wrapper.swf" ...>
<param name="filename" value="path-to-external-swf.swf"/>
<param name="clickTag" value="http://www.example.com"/>

The SWF "wrapper.swf" should load the "path-to-external-swf.swf" an puts a onClick - Event on the whole area.That works just fine, BUT The loaded external SWF should always fit to the stage size (like 100% width and 100% height) .My code looks like this:

Code:
// Variables should be passed by URL
_root.filename = "http://example.com/animation.swf";
_root.clickTag = "http://www.example2.com";[code]....

Code:
mClip._width = Stage.width;

When i click on the swf, the movie fits exactly to the stage width...
