Membership Not Available
"Sorry, but this Membership is not available for the chosen Payment Type."
This error occurs when that pricing option is not set up properly with
the biller or the current cascade has no billers. Make sure the site's
biller codes are correct and the current cascade has at least one biller
in every cascade this site uses.
Empty Payment Type Field
The payment type field goes missing if you don't have any cascades
selected. Go to Sites Admin, click the Edit Cascades icon, mark
one or more cascade checkboxes, and save.
