[vekia]

your module isn;t attached to  hookDisplayLeftColumn

installation function doesnt contains registerhook for this hook.

[JoelWebsites]

Actually I cannot see any output on the page for hookDashboardZoneOne

[vekia]

in your hook function there is no 'return' value, and it's necessary.

take a look how other modules uses this hook

	public function hookDashboardZoneOne($params)
	{
		$gapi_mode = 'configure';
		if (!Module::isInstalled('gapi'))
			$gapi_mode = 'install';
		elseif (($gapi = Module::getInstanceByName('gapi')) && Validate::isLoadedObject($gapi) && $gapi->isConfigured())
			$gapi_mode = false;

		$this->context->smarty->assign($this->getConfigFieldsValues());
		$this->context->smarty->assign(
			array(
				'gapi_mode' => $gapi_mode,
				'dashactivity_config_form' => $this->renderConfigForm(),
				'date_subtitle' => $this->l('(from %s to %s)'),
				'date_format' => $this->context->language->date_format_lite,
				'link' => $this->context->link,
			)
		);

		return $this->display(__FILE__, 'dashboard_zone_one.tpl');
	}
