Hi, guys! A interesting problem: I have a function on my fla that executes many things. All these things depends of a number parameter. Ok. No problem with this. But now I must call this function through a html link at the same flash´s page. So, my way is the External Interface class. When I try it at my local pc, everything is great. But when I upload it, it stops working! The flash code: > // importing the flash external interface: import flash.external.ExternalInterface; // the function: function pedirAnunciante(codigoAnunciante) { // many codes here… } // the addCallBack method: ExternalInterface.addCallback(“pedirAnunciante”, this, pedirAnunciante); The HTML code: > \ \ \ \interna\_javascript\ \
