ExternalInterface returns null values in IE6/7
May 21, 2009 12:00 AM
Check my signature for more detailed examples, there are problems with pulling values into Flash with with ExternalInterface.call() as setting a variable in Flash. This is not a bug, it is a security feature... (I've had to rewrite some stuff to do it differently)
Example:
This will not work:
var myvariable = ExternalInterface.call("ReturnValue()");
