fix the Google Analytics conversion tracking

The goal of the project: Accurate conversion tracking with Google Analytics, Google Adwords and Aweber. This is a simple Javascript/Html job that can be done very quickly. Basically you have to customize the tracking script on my website, which is somehow messed up. I use the turnkey shoppingcart "Avangate" to sell software on my website. The conversion tracking is installed according to the attached files but it is horribly inaccurate. The numbers of Analytics, Adwords are much lower that the actual sales. Aweber is a turnkey e-mail marketing software and can track the sales of e-mail marketing campaigns. Attached are the instructions and code samples that need to be customized. This is a quick and easy job for the right person.
