Mail Chimp Form

I have the mail chimp subscribe form code embeded in the text widget with “first, last name and email” fields and a subscribe button. The problem I’m having is once you enter your information and hit subscribe, you end up on another page with the original mail chimp form…not what I want. I want the widget form to simply add you to the subscriber list, not to another form. There is obviously something I missed on the mail chimp side….any ideas?
