Javascript elements seemingly broken

[CButcher9]

Hi,

I was messing around in the code editor when i probably shouldnt have been due to my knowledge and i seem to have broken Javascript elements on my website? My slideshow will no longer work, my in-cart quantity modifier is gone and none of my hover over drop down menus work anymore. I cant seem to figure out whats happened and reverting my liquid files isnt helping - can anyone take a look for me and see if its anything obvious?
