[Plugin: wp-seatingchart] Plugin conflict issues

I really want to use this plugin but I am having trouble with it working correctly. It is conflicting with another plugin (not the theme, I checked). The code shows up on the post/page but it is set to “display: none” and when I uncheck display: none in firebug, a chart shows up but it isn’t the chart I created.

Here is a link to the site: http://www.camarillohighschoolsports.com/. Maybe you can make sense of it.

thanks!
