Not Working

So I have installed I had to install an ssl certificate, to get where users could sign-up for memberships and take payments, I got that resolved. Now I get to the part where users need to pay for the membership but when users put in their information it doesn't do anything their is no submit, I thought it was the credit card symbol but it doesn't do anything. Is there something I am missing? On other plugins I have used you would put in all your info on the site. Let me know if anyone has any ideas. Any help is appreciated it.
