Hello,
Please forgive me if you have already answered this question. I looked, but couldn't find the answer.
I have the business edition. For payments, I'm using PayPal the Paypal payment plugin. The problem is, in the plugin, it's asking for a price. I don't want to have a set price because it's different with each product. In your documentation, the screen shots don't show a textbox for price, but in the plugin there is.
When I'm on the frontend, and I click on the PayPal option for payment, I'm transferred over to PayPal, but I get an error saying the system is unable to process the payment.
