O.K, newbie question.

I have put the following code into a Page called NewPage.php:

class NewPage extends Page {
static $db = array(
);

static $has_one = array(
);

}

class NewPage_Controller extends Page_Controller {

function newFunction1() {
return DataObject::get("Page", "ParentID=0");
}

}

In NewPage.ss I call newFunction1 by using:

<% control newFunction1 %>

<li><a href="$Link" title="Go to the $Title.XML page"><span>$MenuTitle.XML</span></a></li>

<% end_control %>

When I then access the page, I get the following error:

ERROR:
Error
The website server has not been able to respond to your request.

What have I missed?

well first - open _config.php and add Director::set_environment_type("dev"); so you can see a more useful error apart from the blank error page!

Thanks, the extra debugging info is very helpful. I rebuilt the page it works fine. I think I had a typo....
