actionscript 3 - Toggling one button to adjust two values -

-

i'm designing virtual simulation of physical machine controller has few face buttons. i'm trying arrow buttons scroll through menu , modify selected value when enter button clicked. right now, functions want to, when toggles menu control , scroll through, next value on menu (i.e. temperature 1,2,3) overwritten previous. snippet of code controls selected/unselected functionality, in enter frame event listener:

screenshot

//--switches between scroll , edit--// if (changerswitch == true) {     changermenu = changer;     minvalue = menumin;     maxvalue = menumax;     screenmain.selectedshade.visible = false;     screensmall.selectedshade.visible = false; } else {     changervalue = changer;     minvalue = valuemin;     maxvalue = valuemax;     screenmain.selectedshade.visible = true;     screensmall.selectedshade.visible = true; }  switch(mainmenuindex) { case 0:     break; case 1:     temperature1 = changervalue;     break; case 2:     temperature2 = changervalue;     break; case 3:     temperature3 = changervalue;     break; default:     break; }

mainmenuindex reference number current menu option , set equal changermenu. , down buttons add , subtract 1 value changer. enter button flips changerswitch boolean.

//--face buttons--// ws_btn_down.addeventlistener(mouseevent.mouse_down, f1_menudown);  function f1_menudown(event: mouseevent): void { if (changer < maxvalue) {     changer ++; } }  ws_btn_up.addeventlistener(mouseevent.mouse_down, f1_menuup);  function f1_menuup(event: mouseevent): void { if (changer > minvalue) {     changer --; }   }  ws_btn_enter.addeventlistener(mouseevent.mouse_down, f1_menuenter);  function f1_menuenter(event: mouseevent): void { if (changerswitch == true) {     changerswitch = false;     changer = changervalue; } else {     changerswitch = true;     changer = changermenu; } }

i don't know if best way this, i'm trying results. need in order value next selected menu option remain unchanged?
