Javscript, CSS/HTML troubleshooting - repost

I have a coffeescript which I've translated to Javascript, along with HTML/CSS templates. The scripts are not working as required in Internet Explorer. They were designed to run in Chrome. The developer who worked on these in the past was a ruby developer and was probably therefore comfortable using coffeescript. This isn't working for me, as I am not a Ruby developer and I don't know much about coffeescript either. These issues need to be looked into. Bid only if you have a good understanding of these technologies
