You can try using the Array access syntax to specify the field name. Something like the following:

<mx:String id="str">score</mx:String>
<mx:Label text="{arrColl.getItemAt(slider.value)[str]}" />

Flex Builder may give you a warning saying “Data binding will not be able to detect changes when using square bracket operator. For Array, please use ArrayCollection.getItemAt() instead.”, but you can probably ignore that.

Hey
