ExternalInterface.addCallback

1 
ExternalInterface.addCallback("updateMenu", this, updateSection);
    
    
    function updateSection(newSection){
        currentSection = newSection;
    }

I have a text box that uses the variable “currentSection”. It doesn’t change when I click the button in HTML that calls the function. Anyone know what I’m doing that’s wrong? Is there a working example of this anywhere?

I need a callback of some kind so I can update my flash Nav. I don’t care if it’s externalinterface or now.
