Hello, How can i set the price in my costum form, that will bill the users every month? I've tried manually editing this, but without any luck ( data-second_price ): <input type="hidden" data-first_price="35.00" data-second_price="228.00" name="product_id" id="product_id-0" value="3-3" /> How can i remove the product and set the price manually in my form code? data_first_price will always be 35, but not the monthly.
