subscriptions are not purchaseable? using authorize.net

I have 3 subscription levels on our site:
annual (finite 1 yr, $15)
2yr (finite 1 yr, $25)
test (finite 1 week, $0.50)
all are active and public

The first one seems like it will work, when I enter my CC, the Visa symbol lights up. However, this doesn't happen on either of the other 2 types.

When I click the card icon, which seems to be the submit button nothing happens.

I have authorize.net live on the site and in test mode at authorize.net. Help?
