Using Secondary Screen Branding Theme

Some merchants chose to have a particular store item displayed in the cart utilizing a secondary screen branding theme they have created. This could even be from a totally different Web Store selling the same items.
To accomplish this, an additional parameter must be appended to the buy link in order to have the secondary screen branding theme applied during checkout.
Add this parameter to your buy links that are coming from the secondary domain requiring a different theme (excluding the quote symbols):
"&ThemeCode="
The following example assumes the secondary screen branding theme for merchant account "DEMO" is called "2NDTHEME" and the store item is "BONE".
Example buy link using non default screen branding: http://secure.ultracart.com/cgi-bin/UCEditor?MERCHANTID=DEMO&ADD=BONE&ThemeCode=2NDTHEME.

Here is another example of adding a hidden parameter to a buy form in order to show a different theme:

<form action="https://secure.ultracart.com/cgi-bin/UCEditor" method="post" onsubmit="return validate()">

<input type="hidden" name="merchantId" value="DEMO" />
<input type="hidden" name="add" value="TSHIRT" />
<input type="hidden" name="ShippingCheapestMethod" value="true" />
<input type="hidden" name="BillingSameAsShipping" value="true" />
<input type="hidden" name="ClearCart" value="true" />
<input type="hidden" name="ThemeCode" value="2NDTHEME" />
<input type="hidden" name="ImmediateThirdPartyHandoff" value="true" />
<input type="hidden" name="BillingCountry" value="United States" />
<input type="hidden" name="ShippingCountry" value="United States" />
