flash vertical menu - adding code for scrollpane

Question

I got a flash vertical menu which has auto scroll but it scrolls too fast and the only way to slow it down is to increase the height of the button. I would like to replace the code with a scrollpane so i can control the menu :

CODE:: ** CODE CHUNK I NEED TO REMOVE - THEN ADD THE ADDITIONAL SCROLLPANE CODE- i hope**

menu_mc_Europe.onEnterFrame = function() {
    if (_ymouse>10 && _ymouse<boundry_mc._height && _xmouse>0 && _xmouse<boundry_mc._width) {
     ratio = (menu_mc_Europe._height-boundry_mc._height)/(boundry_mc._height);
     if (_ymouse>boundry_mc._height/2) {
      destScroll = -(_ymouse)*ratio-menu_mc_Europe.bttn_mc._height*ratio;
     } else {
      destScroll = -(_ymouse)*ratio
     }
     menu_mc_Europe._y += Math.round((destScroll-menu_mc_Europe._y)/5);
     if (menu_mc_Europe._y<-(totalBttns*menu_mc_Europe.bttn_mc._height-boundry_mc._height)) {
      menu_mc_Europe._y = -(totalBttns*menu_mc_Europe.bttn_mc._height-boundry_mc._height);
     }
    } else {
     destScroll = 1;
     menu_mc_Europe._y += Math.round((destScroll-menu_mc_Europe._y)/5);
    }
};

END OF CHUNK

Answer 1

hard to read that code w/out line breaks - what does 'ratio' represent above? is it a variable you can set? if not, just a wild guess, but try changing the divisor (the 5) in the '_y)/5' sections above?
