running custom function from hotspot in customized plugin

Hi, I'm basing a custom plugin on the example plugin provided. I wrote a function this plugin swf, and I need to have this called from a hotspot click (set in the xml). I haven't done a lot yet in it beside change the buttons to my graphics, all works great, easy, and have it loading in as a plugin.

I saw the quick examples on the site regarding calling a function writtin in a plugin. I'm a little confused as to which one is correct, I tried both.

I tried this example and set the function to shift the x of a red square just to see if I have a 'pulse' here. nothing. I didn't change anything other than remove the text paramter and add my mc x move.

function myfunction()
{
  test_mc.x = 900;
}
I created a quick test red sq mc name set to test_mc

krpano.set("events.myfu", myfunction);

I set the onclick on the hotspot in the xml to this:

onclick="call(events.myfu);"

I get nothing. The function works, very simple mc move to test this.
