I have a similar problem.

I have followed the tutorial 'Anchors Explained. How to Set Up Annotations', but when it gets to the part where you say about modifying the HTML file, which file are you referring to exactly?

Also having successfully modified Ian Scott's excellent tutorial 'Mixing 2D HTML with a 3D Web Scene'. I have it working locally, but when it comes to deploying the result on a web page I am lost. I just cannot get my Custom Elements, which are working fine locally, to show up on-line. I think I need to call the modified java script, but I cannot figure out how. You talk about modifying the Web Player HTML file, but for us with a limited knowledge of HTML how exactly should this be done?

Assuming I have Ian Scott's example, with all the files, how can I deploy this using the wepplayer.HTML?
