I am in the process of trying to make a scroll bar for an mp3 player, but for some reason, I cannot get the height of the area that needs to be scrolled.

So far, I have set up the playlist area that automatically fills according to all the songs in the playlist. I put a mask on the top of the playlist to keep the extra hidden until it is scrolled to.

The playlist area is called bot  
The playlist mask is bot\_mask  
The song titles and names are added to bot.playlist and when more than one song is in the playlist, it duplicates bot.playlist.

hopefully you can understand that 😛 I just need to know how to get the height of the playlist area after it has finished adding all the song and band titles.
