Third party cart form not passing cookies

[adamnldt]

Okay, I have systematically worked with the developer to slowly address the issues that should be causing issues with tracking between my third party shopping cart and the site I'm working with - dustyscellar.com

For the most part, it seems to have removed 99% of the referrals, but when I tested it yesterday, it appears my order form is not passing along the cookie. Here's the setup:

(you can just look at Dusty's Cellar: Restaurant, Bakery, and Store in Okemos, MI if you'd like to go to the full page)

<tr>
<td valign=top>
<form action="https://www27.safesecureweb.com/dustyscellar/index.cfm?goto=basket" method="post" onSubmit="javascriptageTracker._linkByPost(this) ">
<input type="hidden" name="gift_basket_id" value="38">
<input type="hidden" name="action" value="add">

<table width="300" border="0" cellspacing="2" cellpadding="2">
<tr>
<td width="80" nowrap>

<select class="size" name="size">
<option value="small" selected>Small: $52.00</option>
<option value="medium">Medium: $72.00</option>
<option value="large">Large: $87.00</option>

</select>

</td>
<td nowrap><font face="Times New Roman, Times, serif" size="2">
<b>Quantity: </b> </font>
<input class="quantity" name="quantity" type="text" id="quantity" value="1" size="1" maxlength="2"> </td>
<td width="85"><input class="formbutton" type="submit" value=" Order "></td>
</tr>
</table>


which upon order takes you to: https://www27.safesecureweb.com/dust...fm?goto=basket

as you can see, the link by post function is there, and i've got the setallowlinker in the code:

<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." :
"http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost +
"google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
var pageTracker = _gat._getTracker("UA-6060528-1");
pageTracker._setDomainName("none");
pageTracker._setAllowLinker(true);
pageTracker._trackPageview();
</script>

Any help would be sincerely appreciated. Because as of now I can't see what's referring sales, and that's going to drive me insane!

Thanks.
