In Google Analytics I've set up a Goal Funnel to track visitors that enter the "shopping cart" to the "success page."

I'm having two problems:
1. The funnel is not tracking properly. It only displays a visitor as exiting the funnel at the PayPal step (which the paypal issue is my second question). However, does anyone know why the funnel is not showing a visitor exiting at the steps before the PayPal Step? For example, exiting at the Log-In Step, does not show in red. Instead, the funnel places a link next to the PayPal Step. See image below.


Any idea what is causing this?

2. The PayPal issue. If I understand the instructions on Google, "when exiting a funnel to a third party site, you have to also add some code in two places." One place is the tracking code, which I was able to modify. See modified snippet of code below:

Code:
pageTracker._setDomainName("none");
pageTracker._setAllowLinker(true);
However, the form tag needs to be modified too -see code below:

Code:
<form action="http://newdomain.com/form.cgi" onSubmit="javascript:pageTracker._linkByPost(this)">
The issue is, it seems that the PayPal form tag is generated automatically, when using the PayPal module in Zen Cart. Is there a place to modify the PayPal form tag?

Some info on my Zen Cart:
I'm using: 1.3.8
I've installed: Simple Google Analytics 1-2-3
Remote Server: Linux 2.6.18-165.el5PAE
PHP: 5.2.12 (Zend: 2.2.0)
MYSQL: 5.0.67

Any help would be great. Thanks.
