Calling Flash function from Javascript

["Alain Levy" <webforumsuser@xxxxxxxxxxxxxx>]

Hi everyone, 

 I am desperately trying to call a Flash function (myfunction) from 
javascript... I believe the function has to be made accessible by using the 
addCallback method but when I add these 2 lines of code to my script, the flash 
form does not load.

        import flash.external.*;
        ExternalInterface.addCallback("myFlexFunction",myfunction);

 Any help would be very much appreciated, I am pulling my hair out over this... 
Thanks a lot, 

 Alain
