Text not showing in template

HI

I have made up a template but when I preview it on the page the text is not showing. The header and image show up ok.

   <h3><perch:content id="heading" title="true" type="text" label="Heading" help="This will form the heading for the side panel"/></h3>
 <img src="<perch:content id="image" type="image" label="side image" width="635" height="480" crop="true" />" alt="     <perch:content id="alt" type="text" label="Image description" />" /> 
   <perch:content id ="body" type="textarea" label="Side body" textile="true" editor="markitup" />
