Why are redirects not working with a button

I am using constant contact inside of WordPress. I have an email capture form with a submit button. I am trying to use that button to go to another webpage that redirects to an affiliate page. For some reason when I click that button it just goes to the first page and doesn't get redirected. I have edited my cpanel for that page to redirect where I want it to go but it always fails to do so when the button is clicked. What am I missing?
