I'm having a problem with recurring payments using Authorize.net. Nothing happens when I click on the "next" button to submit the form. I think the problem is with the checkData() javascript code. Any pointers on where to look at troubleshooting this?
I believe there is some javascript conflict causing the issue. Please submit a support ticket sending us admin and FTP account of your site. I will check to see what's wrong and get it corrected for you.
