Flash CS5 AS3无法获得Flashvars

我是新来的相当新的AS3，我发现自己需要扩展fla。这是由第三方写的。目标是访问flashvars，但对于我的生活无法得到它的工作...一直在它的天学习..Flash CS5 AS3无法获得Flashvars

我正在使用的fla是时间线上的代码与2帧。电影剪辑运行到2帧停止。

第2帧是我需要使用flashvar的地方。

我已经建立了一个简单的例子，将填充第二帧的文本框工作正常。

帧1

var my_var:String = new String(); 
my_var = root.loaderInfo.parameters.uploadId;

帧2

然而，当我用同样的方式对我的第三方FLA我得到空的输出。我也没有使用任何TLF文本（我认为）。

我不明白它为什么在一种情况下工作，但不是其他。我认为这可能与周围代码发生冲突，但我不太了解AS来追踪它。任何帮助，将不胜感激。
