no Total sub-category in BIRT Functions

Migrateduser

<p>I have downloaded BIRT Designer 4.4.0 of all-in-one from <a data-ipb='nomediaparse' href='http://download.eclipse.org/birt/downloads/'>http://download.eclipse.org/birt/downloads/</a>.</p&gt;
<p>And I fellow this demo (<a data-ipb='nomediaparse' href='http://demo.actuate.com/demos/EclipseDemo/EclipseDemo.html'>http://demo.actuate.com/demos/EclipseDemo/EclipseDemo.html</a>).</p&gt;
<p>But when I set data binding and edit expression, I do not find a sub-category of Total which should belong to BIRT Functions. Could you could tell me where it is?<br>
