connect KeyboardEvent to visible false/True button

[Arioman]

i use simple script to Hide Prev Button in First Frame and Next Button in Last Frame

Prevbt_forproduct.visible = false;
nextbt_forProduct.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);
function fl_ClickToGoToNextFrame(event:MouseEvent):void
{
    nextFrame();
     Prevbt_forproduct.visible = true;
     if(currentFrame == totalFrames){
     nextbt_forProduct.visible = false;
}
}
Prevbt_forproduct.addEventListener(MouseEvent.CLICK, fl_ClickToGoToPreviousFrame);
function fl_ClickToGoToPreviousFrame(event:MouseEvent):void
{
    prevFrame();
    nextbt_forProduct.visible = true;
    if(currentFrame == 1){
    Prevbt_forproduct.visible = false;
}
}

and i use Keyboard Function for Add Right and Left Key for Go to  Next and Prev Frame

import flash.display.Stage;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard
stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);
function keyHandler(e:KeyboardEvent):void
{
switch(e.keyCode){
case Keyboard.RIGHT: nextFrame();break;
case Keyboard.LEFT:prevFrame();break;
}
}

now The Problem is , when i use Keyboard to Change between Frames the nextbt and Prevbt are not change , in other mean it does not matter how much i press Right or Left key the Prevbt Button Not apear ( frames changes well )

So how can i set a connection between these Scripts ?

thanks

use:

Prevbt_forproduct.visible = false;

nextbt_forProduct.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);

function fl_ClickToGoToNextFrame(event:MouseEvent):void
{
    nextFrame();
nextPrevF()
}
}


Prevbt_forproduct.addEventListener(MouseEvent.CLICK, fl_ClickToGoToPreviousFrame);

function fl_ClickToGoToPreviousFrame(event:MouseEvent):void
{
    prevFrame();
nextPrevF();
}
}

import flash.display.Stage;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard

stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);

function keyHandler(e:KeyboardEvent):void
{
switch(e.keyCode){
case Keyboard.RIGHT: nextFrame();break;
case Keyboard.LEFT:prevFrame();break;
}
nextPrevF();
}

function nextPrevF():void{

if(currentFrame!=totalFrames){
 nextbt_forProduct.visible = true;
} else {
nextbt_forProduct.visible=false;
}
    if(currentFrame == 1){
    Prevbt_forproduct.visible = false;
 } else {

  Prevbt_forproduct.visible = true;

} 
}

Dear Kglad i have one Question

is there sorting of Script Important ?

i`m curious about this cause i see you put :

import flash.display.Stage;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard

in middle of script ( right before keyboard Event ) , is it wrong if i use these in top of my script ?

it's not critical but, by convention, import statements should be at the top of your code.
