I've tried a number of different things but I can't seem to solve this issue.

I setup a payment option and when I call GATEWAY.setup_purchase(subtotal, options) I get the following error:

wrong number of arguments (1 for 0)

the relevant stack info seems to be:

vendor/bundle/ruby/1.8/gems/activemerchant-1.20.1/lib/active_merchant/billing/gateway/paypal_express.rb:97

this person seems to have the same issue, but there has been no response:
