FlashDevelop won't build project?

[GrahamNG]

My project tree includes a folder called 'AS3 OOP (AS3)' and a 'DocumentClass.as' which is inside it.

This is what's on 'DocumentClass.as':

package{
	import flash.display.MovieClip;
	import flash.text.TextField;
	public class DocumentClass extends MovieClip {
		public function DocumentClass() {
			var tf:TextField = new TextField();
			addChild(tf);
			tf.text = "Hello World";
		}
	}
}

When I try to build the project I get this information pop up:

'In order to build this project, you must mark the AS or MXML entry point as "Document Class" in the project tree.'

So, what do?

Did you right click the file and set as document class?
