Adding total and elapsed time to a custom skin in FLVPlayback

I have this player and I am using the FLVPlayback. I have tried to include this code in the skin to see the time displayed there, but it doesn't work. If i use this code in the player itself, it works fine but if i place the text zones in the skin to display the time it doesn't show anything. I am at my wits end. how can i make a skin show the total time and duration for a FLVPlayback player?
