Integrating The iGOshopping/PayPal Shopping Cart Into Your Site
To Integrate the iGOshopping shopping cart into your site you can build your page anyway you want.
Make Sure You Save Your Page With .shtml As The Extension.
You will use the following template in one or more places in your page where you want the cart tables to appear. This Is A Link Example 
<!--#include virtual="cgi-bin/paypalstoretemplate?item=CAKE1&choice=normal&number=1&showborder=no&showtitles=no&showsku=yes&showpicture=yes&showeight=no&showdescription=no&showprice=yes&font=normal&fontsize=2&orderlinktype=image&imageorphrase=addtocart.jpg"-->
paypalstoretemplate offers a lot of flexibility in the design and look of the store item.
This line also loads the items from the database right into your form. There are many paramaters you can change, but you have to have them all and in this order:
  1. category= This can be any category in your database or if you change it to item= you can specify a specific sku
  2. choice= random or normal
  3. number= the number to show
  4. showborder= put a border around the items
  5. showtitles= show titles
  6. showsku= show sku
  7. showpicture= show the small picture
  8. showweight= show the weight
  9. showdescription= show the description
  10. showprice= show price
  11. font= this can be like Ariel, etc.
  12. fontsize= normal or 1-7
  13. image= this is the image. The image is in the store root so if I were putting http://www.igoshopping.com/add.jpg I would only put add.jpg here. If I were putting http://www.igoshopping.com/images/add.jpg I would put /images/add.jpg here.
Any field value that has more than one word separate by a plus sign. For example if category was "Candied Deserts" I would put

category=Candied+Deserts

for that particular field.

The Most Wonderful Cake [an error occurred while processing this directive]
Here Is The Code 

<table border>
