[Plugin: Vote It Up] Error: vote is not defined

Hi, I’m using Vote it up plugin on my WP site and when i click the “vote” button is showing the following error on my Javascript conslole (in Firefox)

“Error: vote is not defined”

To do a test you can go to
http://www.florda.com.ar/belgrano/comercios/donna-bella-estetica/
and click over the “Valorá este beneficio!” link

Any idea ? I suppose there is a conflict with javascript, but not sure how to solve it.

Thanks
