[Plugin: WP Stripe] Received unknown parameter: amount

When submitting a charge via the inline form (<?php echo wp_stripe_form(); ?>), it appears to try to submit it and then I get a “Received unknown parameter: amount” error and the charge won’t submit.

I’m in test mode and I’m able to create charges via Stripe’s control panel without issue.
