IE ColorBox Scroll Bar Not Showing Up

I am using a colorbox modal on the "SAMPLE SAVINGS" Link and the Scroll Bar is not showing up for users with IE 8. Also the same users see "Javascript jQuery errors".

I'm开发者_如何学运维 not sure how to target for this browser specific error. Anyone know?

I this is the page I am working on currently (please take a look in IE):

CLICK "Sample Savings"
