Error calling javascript function using ExternalInterface.call

programming flash
1

I’m attempting to execute Javascript code (the fromFlash() function) that’s in an .HTM file, in which is embedded my .SWF file. I’m using the following code in the .FLA file:


myButton.addEventListener(MouseEvent.CLICK, runExp);
function runExp(e:MouseEvent):void {
 ExternalInterface.call("fromFlash");
}

When, from the .HTM file, I click myButton, I get the following error:

SecurityError: Error #2060: Security sandbox violation: ExternalInterface caller [file:///C:/_Flash/email/email.swf cannot access file:///C:/_Flash/email/loadFlash.htm](file:///C:/_Flash_learning/email/email.swf).

Any insights?

Thanks!
