Advanced Options:

(Advanced used may have different settings. Check with your project manager if you have questions) 

The Shopper Group option allows you to make this payment processor available only to a specific shopping group. By default it is assigned to the default shopper group. This would be changed only if you wanted to offer a specific shopper group this payment option.

The Discount field is where you would set a discount that would be applied during checkout at the time of payment.

The List Order is for the arrangement of multiple payment options. For example; if you are offering 2 different payment options and you wanted this payment option to be 1st in the list, you would enter “1” in this field and put a number greater than 1 in the other active payment processor(s).

Save and Check Activation States. Of course, Click the ‘Save’ button after making your changes – and be sure that this payment processor is set to “Active” and any other payment processors that you do not want to use are set to “Not Active” (Unpublished).
