Membership subscribe button isn't showing on the subscribe form.

My membership plugin isn't showing the subscribe button. I can select the subscription, fill out the form and select continue. It then asks me to confirm information and press the appropriate button. The button isn't there. I have checked that all levels are active, all subscriptions are active and the two i want visible are public. I activated the authorize.net plugin and filled in all the information. I don't know what is preventing the button from showing. I made sure membership was enabled too.
