TOPIC: Tracking PayPal with Google Analytics

Hi
I would like to setup DT Register to work with Google Analytics so I can do Goals. In order to make this work some setting have to be changed in Pay-Pal. Mainly "Auto-Return On" but the DT Register payment manager has instructions to turn "Auto-Return OFF". Does it matter if the Auto-Return is OFF or ON?

[url]Tracking Instructions[/url] - FYI

Also does any one know the Payment success thank you page URL built in to DT Register?

Thanks

I need this as well, are there ways to do this currently via special URL parameters, Thank you Page settings in DTR or doing it in PayPal or other payment system? Please assist, we can't do any kind of ROI tracking if we don't match payments with visits in Analytics
