[Forums] Adding Java script to a page to refresh it

no, check out the fakenotifywidget (webblock) in richwidgets.

place that webblock on your screen with a name (for example 'fake' )
this will also need a onchange desitination, which will be the screen-action where you refresh the webblock.

then in the code

<scripttype="text/javascript">setTimeout(function () { 
      OsNotifyWidget('" + fake.Id + "','some dummy message or empty');
    }, 3000);</script>
