2 functions to one button

hi, i have to scripts each in a different movieclip, i have

 
_root.navigation_n_logo["next_btn"].onRelease = function() { 
nextImage(); 
}; 

and

 
_root.navigation_n_logo["next_btn"].onRelease = function() { 
galleryChoice(2);
 };

so as you see, I want both functions to execute on the same button
but it only does 1. how can i fix this? so that both functions execute on the same button/movieclip

allready thanks…
and sorry for my english :cantlook:

matt =)
