Hello -
I am running DNN version 7.1
I believe the default version of jquery added to this installation is 1.9.1

My question is this:
There are certain pages on my site that are throwing jquery syntax errors on page load. In IE, these pages produce a pop-up showing that an error has occurred, and asking if I would like to debug.

You can view this error in action at:
http://www.yandasmusic.com/dd/productid/7318/elixir-polyweb-coated-super-light-electric-guitar-strings-09-42-gauge-12000

Is it the version of jquery I am using that is causing this error? Based on these errors, what action would you suggest I take?

The specific errors thrown in IE are as follows:
Error:Syntax error, unrecognized expression
Error: Unable to get property 'substring' or undefined or null reference.

Thanks! Alex
