Enfold script problem help URGENT!!!

Hi guys I need help with a script problem.

I have an email marketing platform call Guubie and we have a JS button for subscriptions,

This is the page http://guubie.com where you can see the button is not taking the css and either the javascript
but if you go to this url http://guubie.com/imap/button.html you will see the same code but this one works.

I check the developer panel of Safari and I get this error

[Error] TypeError: ‘undefined’ is not a function (evaluating ‘$(“select”)’)
global code (guubie.com, line 165)

[Error] TypeError: ‘undefined’ is not a function (evaluating ‘$(“#octsmartsubscribe-button”)’)
applyButtonStyles (subscribe.min.js, line 2)
init (subscribe.min.js, line 1)
onJQUERYload (subscribe.min.js, line 26)

Why it works outside of enfold? any idea?
