Payment Field [Selling Subscriptions]: Focus on the amount field when selecting subscription with variable price.

Second, even whem I choose to put a price in the subscription, the focus does not goes to this option, the user has to click there.

I will forward this to our second level since it's not possible to do at the moment, though we cannot provide an ETA about when this could be implemented, we will let you know as soon as we get any new about it.
