Slider is not working in Internet Explorer.

Hi,

I have spent a few weeks modifying the Zenon Pro template to my own specifications. Everything seems to be working fine so far, except when I check the website in Internet Explorer the Slider appears to be shrinking the image and not working.

Here is a link to the website: https://dev.oonasboston.com

How do I fix this? I am stumped. I have spent about 3 days trying to figure it out!
