Hi,  for example you have few components on the stage and you want to run different effects on them. So lets imagine we have label1, label2 and label3 and we want for example make label1 move to some place and after that animation is finished we will fade out label2 and label3 simultaneously.

So we can use Sequence and Parallel effects in Flex, to do this see code below:

<mx:Sequence >
	<mx:Move target="{label1}" yTo="0" duration="1500" />
	<mx:Parallel duration="2000">
		<mx:Fade target="{label2}" alphaTo="0" />
		<mx:Fade target="{label3}" alphaTo="0" />
	</mx:Parallel>
</mx:Sequence>

So why I’m telling this ? This is very simple, but there is a trick you always should use there this syntax target=”{…}” instead of target=”…” other way it wont work and you will be getting Error #1006 Value is not function.
