Topic: I can’t change・・・

I bought  TiltViewer-Pro.
However, the fontsize and linkLabel, etc. cannot be changed.

Anything doesn't change even if it sees in a browser though the following part was changed.

        //fo.addVariable("linkLabel", "View image info");

        //fo.addVariable("titleFontSize", "90");

It did not change though the cash of a browser was deleted, and up-loaded to the server.

Please teach someone ..understanding...
