Forms within GK-Tabs not working

Hello,

I'm trying to use GK-tabs with different menus in different tabs. The menu only works in the initial tab, but it I go to another tab, selects are not selectable and nothing happens when clicking on a checkbox.

http://www.qsfc.com.au/dev/html/ here is the link I'm working on. The form works on the initial tab "Fixture" but doesn't in other tabs; "Ladder" and "Register"

Thanks in advance

Hello,

I afraid that it is an issue with your content inside the tabs - because the elements are not overlayed by any other element and are accessible but don't work.
