1180 Call to a possibly undefined method navigateToURL
If you get the above error when trying to run your flash actionscript 3 file, you are obviously trying to use the navigateToURL() function but have not imported the flash.net library code.
The following code before everything will correct the problem.
import flash.net.*;
..or a more of a direct unbloated method is as follows:
import flash.net.navigateToURL;
