Embed tag not working

programming flash
1

I’m trying to embed a swf into my AS3 project to access the swf’s library.


[Embed(source="UILibrary.swf", symbol="EffectsBtn")]
private var EffectsBtn:Class;
//...
//EffectsBtn then gets added to the stage in the main function
var effbtn:Sprite = new EffectsBtn();
addChild(effbtn);

However it never shows up on stage and I don’t get any errors.
