how do I change the PayPal account email address associated with our JotForm account?

I need to change the PayPal account associated with a couple of different forms we have created lately.  How do I go about doing so?

While editing your form, click on the payment field, then click on the wand icon to the right of the field.  That will bring up the payment field menu.  From there, click the gear icon in the top right of the menu.  From that menu, you can change the email address being used in the PayPal field:
