Yeah Basic Post was the only option on the method i am using and i didn't understand what Merchant ID meant, also wasn't clear on what secret word meant either, i am guessing password right?
Where can i locate the merchant ID or account ID? I will also call 2checkout tomorrow to ask and make sure i did everything correctly.
Is that code somewhere on the cart page then or how to i fix this error once i have my ID?
Thank you sir
