[flexcoders] Passing id to a function

[Sandy Saline]

When I click on a canvas that was created dynamically and given an id, I
am trying to pass the id on to a function that changes the alpha value
of the canvas. 

 

I am using an EventListener and var myID:String =
event.currentTarget.id;  When I use a trace statement, I know the id
value is being passed correctly.

 

This is the point I get stuck at. How do I use this var to change the
alpha value dynamically? 

 

TIA for your assistance.
