I was trying to transfer data form the html to the panorama to make a "mute button" called from a link in the html where the pano is embed. Iwas using the Krpano example...(https://krpano.com/examples/javascript2/), but after some hours without success, I decided to take all the code to test what I was doeing wrong. so I took it and changed just the rutes to the files... but it's not working... anyone can say me what is wrong? or any idea to make this mute button called externaly from a link?
thank's a lot, and sorry for my english!! 
This is the code I was talking about:
<html>
<head>
<title>krpano.com example</title>
</head>
<style>
body{ font-family:Arial, Helvetica, sans-serif; font-size:14px; color:#333333; background-color:#FFFFFF; margin:20; padding:0; }
* html, * html body{ overflow: hidden; }
a{ color:#000000; text-decoration:none; display:block; padding:5px; margin:1px; border:1px solid #666666; background-color:#AAAAAA; cursor:pointer;}
a:hover{ color:#000000; text-decoration:none; background-color:#EEEEEE;cursor:pointer; }
table{ font-size:14px; background-color:#000000; color:#FFFFFF;}
</style>
<body>
<center>
