Conditions: Is there a way to set up multiple options based on quantity selected for items in a payment wizard?

Within the payment wizard, I have several products, with an option to select the quantity and flavour from drop-down boxes.  However, I'd like to allow my customers to select multiple flavours if they choose more than 1 for the quantity (for example, if someone wants to purchase 2 items, and they'd like one to be chocolate and one to be vanilla).  Is there a way to do this, so whatever number they choose for the quantity has the option to select a corresponding flavour?  

I assume you are referring to this form (http://www.jotform.ca/form/60118200270236). As per checking the payment integration settings, I'm afraid that it is not possible to have a condition inside the payment field.

Alternatively, what you can do is to set up the conditions and calculations outside the payment field. Then, pass the total amount to the payment field.

Here are the guides that will help you to achieve this on your form:
