I 'm writing some html code to build a shipping calculator for my templates that will send information from my auction pages (item weight, handling fee, package size, etc.) to eBays calculator that will display shipping costs to potential buyers. To do this I will need to use a script that part of the code that can be found on eBay auction pages. I have found that I am able to build the calculator.
My question is, will I be violatiing any eBay rules or otherwise doing something else wrong if I use the calculator in my auctions? I certainly don't want to get in trouble for using some of eBay's code to build the calculator but I really need a calculator for my buyers to use. What are your feeling on this?
