Hi all,

[COLOR=black]The only code I changed was[/COLOR]

adding in the following to the \<mx:bubbleChart tag  
[SIZE=2]selectionMode="[/SIZE][SIZE=2][COLOR=#990000]multiple[/COLOR][/SIZE][SIZE=2]"  
[/SIZE]  
and making by bubbleseries selectable  
[SIZE=2]bs.selectable=[/SIZE]**[SIZE=2][COLOR=#0033ff]true**[/COLOR][/SIZE][SIZE=2];[/SIZE]  
[SIZE=2][/SIZE]
