Solution to Invalid Flash:trace () statement

Solve | The statement that things happen like this ...
When you modify the code for a friend, you find that the variable returns an exception, and when you add trace () in the relevant location, the result is invalid. So I'm scrambling to check the code, because trace is embedded in the function, so ......#!! ) #￥*￥ # (! After
But in the first frame add trace (), unexpectedly also invalid!!!!!!! So that is the Flash software set up a problem!
Check the file publishing settings to check for omitting the trace code entry. Try again, pop-up "output" window, still have no content.
So the fantasy text is the same as the background, drag the mouse to select text, without any content. Use the Output window of the right corner menu to save to the file (if you want to be the same as the background, it will be saved as a document to look outside) No fruit! Despair!
Later in the unintentionally found Output window of the right corner menu-> Filter Level-> detailed success!
Write it out and give it to the same situation friends see
