Hi, I have read through the forum and the answer is not clear to me. I just installed the AddContact php script. I have it implemented just fine. BUT when someone is already a contact in the account they cannot sign up for the list I am promoting. It says System Error Encountered! ...already a contact, etc. So, unless the user is a completely new user to the account, their sign up will be denied. It is important that all people signing up through this form get added to the list. I have an autoresponder set up to this list and it is for a specific event they are interested in. What is the code to allow contacts who are already in this constant contact account, under another list, to be added successfully to this new list via the sign up form that I created the api for in the first place? Thanks in advance for your help. ... View more
