How do I setup product quantity fields?

For the products I have in my form, I want the user to be able to select more than one as a quantity. The user would populate the desire quantity and the form would auto calculate a sub-total, based on the single product pricing.

Here's our guide that would help you add a quantity and other options in the payment field: http://www.jotform.com/help/225-How-To-Add-Options-In-The-Payment-Form.

Thanks
