Hi, if you  look in the ebay module folder you will find a folder called override then folder classes, you will need to manually merge the cart.php override set_state into the existing class.php override in your overrides folder.  Then in the ebay folder rename overrides to _overrides, then try install.

 

Note: if your modules override folder has more than one override then don't rename it, rename Cart.php to _Cart.php.

Thank you for taking the time to respond. I hate doing this but can you please translate what you are saying? "manually merge", set_state? How do I know if I have more then one override? Since the eBay Mod is uploaded do I need to upload anything else?
