Setting up ringtones for contacts

I recently bought this phone and I am having trouble setting up ringtones for individual people in my contact list. I use the site www.myxer.com to get my ringtones as I have on previous phones, just having trouble figuring out where to go to set it to specific people. I've tried going to a specific contact and seeing my options, but nothing sticks out to me.

Thank you,
Evan

If you are using Google contacts to populate your contacts list you will not be able to assign ringtones to the contacts.  The workaround is to add a new contact and select "Phone" instead of Google and just name it the same as the Google Contact.  Just the name, you don't have to add any numbers.  No go to your contact and on the top of the screen touch the Phone tab.  There will be an option to change the ringtone.  It will only show up once in your contacts but it is tabbed for Google and Phone. Strange but it works.  For some reason you can't add a ringtone to a Google-only contact.
