swf and passing variables

[tupawk]

Does anyone know if it is possible to pass variables between flash movies using the php swf module?

I have a defined a button but when I do swf_onCondition (ButtonEnter); I can only get it to use the predefined swf_action functions, ie: swf_actionplay ();

Here is an example of what I want to do:

//This loads a movie in level 1
swf_startdoaction ();
swf_actionGetUrl ("test.swf", "_level1");
swf_enddoaction ();

/
This is sets the target to the movie loaded above and should pass the variables $b and $c to that movie. This is also inside a properly defined button omitted here for brevity.
/
swf_actionSetTarget (_level1);
$b = 12345;
$c = test;
