		be price*quantity.  

		

		there are keywords that can be used:

			

			1) "_input" - the field will be a text input with the value set to the given field. when the user

				changes the value, it will update the cart.  this can be useful for quantity. (ie "Quantity_input")

			

			2) "increment" - a link with "+" that will increase the item quantity by 1

			

			3) "decrement" - a link with "-" that will decrease the item quantity by 1

			

			4) "remove" - a link that will remove the item from the cart 

			

			5) "_image" or "Image" - the field will be an img tag with the src set to the value. You can simply use "Image" if

				you set a field in the items called "Image".  If you have a field named something else, like "Thumb", you can add

				the "_image" to create the image tag (ie "Thumb_image").

				

			6) "_noHeader" - this will skip the header for that field (ie "increment_noHeader")
