Sound, Left and right speaker

Hi Kirupa Admins!
I need some help to make a bar that controlls the sound that comes out from ether the righ tor the left speaker so If the bar is 100% left the the right speaker doesnt play any sound but the left is playing to 100%! (just like your “volume bar” tutorial but I need a Tutorial for right/left sound!

Thank you!
