Need help with button to call other mc

Can someone please help me out I’m trying to figure out how to make a button change the background color. I made the mc for the colors to change with the istances set up I just don’t know to have the red button call the mc movie to play the red background.

on (release) {

  		  nextFrame(red);

   

  }

   


Is what I’m using but it doesn’t work. The color move clip is called mcColor and the drop down menu I’m using is called menu.

CAN SOMEONE PLESE HELP ME WITH THESE BUTTONS
