It has to do with the timing of everything. The last example code of your SWF was: var t:String; // which sets to undefined myText.text = t;
So when the SWF's first frame plays it sets myText.text to "undefined". It seems that your SWF goes on past the first frame ( or stops execution ) before the Loader.content gets to set the variable "t". So the execution sequence would look something like this: Loader calls SWF. SWF calls first frame action script and sets myText.text = t (which is undefined) SWF moves on to or stops executing first frame actionscript. Loader.content.t is set. Now myText.text = t is never called again and the new value is not set. In the case where you call myText.text directly you are not setting a variable that has a execution based on some timeline but directly to the correct value you want to change. An alternate is do: progress="event.target.content.t ='Hello World';event.target.content.gotoAndPlay(1)" But the setting of variables directly is much better. Talking to loaded SWF's are not exactly like FlashVars because it depends on the nature of the SWF where things are initialized/set.
