Centering impossible

[Grimholm]

Hi,

I've created a news letterbox with the dimensons 421x85, which only contains two quickslotbars and the experiencebar. The letterbox is supposed to be placed centered at the bottom but I can't get it working as it should. I've attached the current result and here's my xml-code:

<PanelFile ID="toolbar">
	<Element ID="ToolbarField" Width="421" Detach="0">
		<Element ID="ToolbarFieldMain" Width="421"></Element>
			<Element ID="LevelMeter" Width="409">
				<Element ID="LevelMeterFill" Width="409">
				<Element ID="LevelMeter_BonusMeter" Width="409"></Element>
			</Element>
			<Element ID="ToolbarButton_LevelUpXP_TutorialHighlight" Width="409"></Element>
			<Element ID="ToolbarButton_Experience_TutorialHighlight" Width="409"></Element>
			<Element ID="LevelMeterText" Width="409"></Element>
		</Element>
	</Element>
</PanelFile>

Thanks for your help
