When you call a value out of an external xml sheet you end up with a value in Flex's variable

Code:
protected function dataGrid_creationCompleteHandler(event:FlexEvent):void
{
	getDataResult.token = your_file.getData();
}

<fx:Declarations>
	<s:CallResponder id="getDataResult"/>
	<your_file:Your_file id="your_file"
	fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)"
							 showBusyCursor="true"/>

</fx:Declarations>
My Question and problem is I can't seem to get the value into a number variable to enter (in place of the number) in the function below. I am a seasoned php/mysql guy and seem to be missing something basic here.

Code:
TweenLite.to(fill, .8, {y:"-290", delay: 0.1})
