Thanks for posting, I am sorry to hear you are having trouble with your button. Can you help with some details?
- Where did you copy the URL from?
- Are you inserting a custom image as your button or a standard JMML button?
- What happens when you click this button? Do you see any errors?
- Are you testing in the edit mode? If so, tbhe button wouldn't work until you were in the preview mode of your email.
