I can't hit the back button during the place an ad/auction process?

Problem:

Why can't I hit the back button and change the attributes of my ad placement or auction placement?

Solution:

The software is designed to track the progress of the place an ad/auction process so that if a user does not finish the process for whatever reason within one hour, they can come back to the site and continue where they left off. Because of this feature, the progress has been set and going back will not change what has already been set. However, the user has two choices if they want to change something.

1. Click cancel ad/auction placement and start over(obviously only used if the user has not gone very far)
2. Once the image form has been completed the user can edit the category, edit the details entered, and edit the images entered through these function links at the bottom of the subsequent pages after the images form.

You may want to add this information to a FAQ's page on your site as well as to your instructions during the place an ad/auction process if you are worried that your users will become confused.
