Go back to the page contents script. As you can see, the newly created items now show up on the right hand side when their item container is selected.

Select the "HTML header" item on the right hand side and click the "Add item to page" button. The item will appear in the main page window on the left.

Select the "Hello World" item on the right hand side and click the "Add item to page" button.

Select the "HTML Footer" item on the right hand side and click the "Add item to page" button. You should then have all three items in the order in which you added them to the page.

Your next step will be to number the items in the order that they are to appear on the page. Type a number in the box to the left of each item and click its "Move" button until your items are in the order that you wish them to be output to the browser. In our case the items were already in the right order so clicking on the "Renumber" button will order them in multiples of ten.

Once you have the items in the right order, click on the link in the top section of the page to test it by bringing it up in a new browser window.
