Help with your "Complex Button RollOver.." tutorial

Hi there :hr:

I’m a newbie to flash and your tutorials have really helped me out, thank you so much!!
I’m now trying this one: [FONT=Verdana][SIZE=4][COLOR=#003366]Complex[/COLOR][/SIZE][/FONT][FONT=Verdana][SIZE=4][COLOR=#003366][/COLOR][/SIZE][/FONT][FONT=Arial][SIZE=2] [FONT=Verdana][SIZE=4][COLOR=#003366] Button RollOver/RollOut Effects[/COLOR][/SIZE][/FONT][/SIZE][/FONT]
But I don’t understand point xii: “[FONT=Arial][SIZE=2]Navigate back to the root timeline. Put an instance of mc_complex from the library onto the stage.” What am I supposed to do? How can I put an instance anywhere??

thanks for help
