Get my existing jQuery script to work on Wordpress Site

General information for the website: Chess Website
Kind of development: Customization of existing website
Num. of web pages/modules: 1
Description of every page/module: I have written a working jQuery script to run against a formidable form plugin. The plugin is installed but throwing a few errors, I need help tracking down these errors and getting my custom script to run as it adds additional validations to the form:

Here is my custom jQuery code which I need to get working: http://jsfiddle.net/Webby2014/y858g/21/

Here is the current page (which is not currently working): http://yorkshirechess.org/fantasy-chess-olympiad-2014/fantasy-chess-olympiad/

Basically I need help getting my jQuery working and needs to be complete in the next 4-6 hours ideally. This may require the live wordpress site to have jQuery updated.
Description of requirements/features: 1. update jQuery on wordpress site
2. add custom jQuery (which is already written)
3. check formidable form is working as expected.
