Use the Refresh element to specify that your page should refresh—by reloading the current page or going to a different one—automatically after a certain amount of time.
Delay Is the time in seconds to wait before refreshing the page. To refresh the page immediately, enter 0 in this field. Note that leaving the field blank does not have the same effect as entering 0.
Action Specifies whether to go to a different URL or to refresh the current page. To go to a different URL, click the folder icon to browse to and select the page to load.
