Could someone please help me?
Thanks,

) I had four drawscreens - one after each currentpaddle set. If you have only one paddle, you need only one drawscreen, but you should set currentpaddle before you do the drawscreen, and paddle will be read during that drawscreen. I don't know if you only have a one player game whether you'd need to keep setting currentpaddle, though. But I'm assuming for 2 players, you'll need to set currentpaddle then drawscreen then do something based on paddle value that was read, then set currentpaddle then drawscreen then do something based on paddle value that was read.
