Can I set up a recurring payment option in the same form as one-time payment options.
I think it could be possible, since in a multiple payment form you are adding the another payment options using the IFrame method, then you can only send the payment amount or in this case the subscription amount to the payment field and then the user will be subscribed to it.
Take a look to my sample form here, I have added to different payment options, PayPal with recurring payment and a Purchase Order with a single payment : http://www.jotformpro.com/form/53497306922966
Hope this helps.
