I'm working to convert all of our forms to this payment method and I'm having trouble getting the "total" to display.

I'm working to convert all of our forms to this payment method and I'm having trouble getting the "total" to display. Where is this feature configured? One of my forms can be found here: https://secure.jotformpro.com/MerionVillageAssociation/TShirtOrderForm

To show the Total amount on the payment field, please follow the steps below:

1. Click the wand icon of the payment field.

2. Click the Gear icon to edit the integration.

3. Select the Additional Gateway Settings 

4. Set the "Show Total Price on the Form" to Yes.

Continue and save the form then you're all set. The Total Price should now be visible on your form.
If you need further assistance, please let us know.
Regards.
