I use on online reservation system which is hosted on my website. The portal is www.mauitradewinds.com/RezEasy/rezeasy.html
When a guest is in the process of making a reservation, contact details are filled into a form (checkout.html). Then the guest may submit the form or else make changes before submitting. If they modify their reservation (cf0001.html) and save changes, they should be returned to the checkout page, still fully populated with their contact details. However, when I test this, the contact details have been lost and the form is blank. The reservation can't be submitted without filling in the entire form again. Is this only happening on my computer? If it is happening generally, is there a way to preserve the details on the checkout page so a user doesn't need to fill them in again after saving a change?
