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

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

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

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.

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