Why the following JQuery does not work on IE browser when I put it in my website?

I am using DDCharts JQuery plugin to put some charts in my website. I downloaded the plugin and the original files and examples work fine in Internet Explorer 8+ but when I included in my website, it did work on IE but it worked well on Firefox and I don't know why??!!!!

This is my code:

PSI - Dashboard

Try putting your javascript at the end of the page instead of the start. IE has problems when you try and run scripts on elements that haven't loaded yet.
