If the pages of your unit are not listed in the proper order (this is likely to happen if you did not create them in the order you want them to appear), you can quickly rearrange the order of the pages by selecting the unit and clicking the "Order" command. You will see a form which shows the titles of each of the pages in the unit. Simply drag the titles up and down the page until they are in the order you want. Click submit to save your changes.
