Mailchimp Set in OC

Hi,
Does anyone know a guide or can help me set Mailchimp on OpenCart? I installed "MailChimp Integration" but does not function. What can I do?

thank you all

Roberto

Did you use my MailChimp Integration extension? If so, you can contact me at www.getclearthinking.com/contact with your order number for support.

If it's a different MailChimp Integration, then you'll need to talk to its developer. It likely has a conflict with something else you've installed, or a bug that is preventing it from being usable.
