Charge 2 form that has multiple one of plan amounts? I have been trying to set up a Charge 2 payment form and have it all working except for giving the user 3 different plan amounts at the end of the form.

For example, I need to offer the following in a select box or radio buttons at the bottom:


Plan A at $10.00
Plan B at $20.00
Plan C at $30.00


This is relatively simple using subscription modal, but I only want it to be a one off payment rather than daily, weekly, monthly or yearly.  Is this possible?
check out the docs here - http://squarebit.co.uk/software/craft/charge/usage/reference/payment-options and note this bit:


  planIntervalCount accepts int The number of periods for a recurring
  plan. If you're creating recurring charge, this is required, and must
  be 1 or higher. Not including, or passing a 0 value will create a
  one-time charge.


So, you could do

&lt;input type="hidden" name="planIntervalCount" id="planIntervalCount" value="0"/&gt;


for a one off payment.
