Peekaboo sidetables for forumotion

Hello, recently i changed from jcink to forumotion and I was trying to make peekaboo side tables on my site but for any reason they are not working at all, here is the full code I'm using:

In hide:



Here is the link of the site I used before on jcink:

In hide:



And here is my test site on forumotion:



I think the problem is in the JS, i put the code in the templates but nothing, I put it on a javascript page but still nothing, I link the JS file and uploaded in different hosts such tumblr for example but still not running and I can't understand why because the code is correct and in my jcink site it runs perfectly.

If someone could help me I would be very grateful.

Thanks.
