jQuery conflict Uncaught TypeError

jQuery conflict Uncaught TypeError

Hi,

I created on my frontpage a row with icons, when you click on the icons you will see more information about the subject. But the problem is now after creating this script that it doesn't work very well. I get the following error in my inspector:
  1. Uncaught TypeError: $(...).visible is not a function
  2. Uncaught TypeError: $(...).loadPage is not a function(anonymous function)
Could anyone explain what's missing in this script? I've tried to add the no-conflict mode in jQuery but I can't get it working.

I created this script local and from there it works quite well.
