Please Give me Idea for next , prev bt in specific case

Question

hi
i have a movieclip with instance name : content
in this movieclip i have Layer "slides"
and in frame1 of this layer  i have movieclip called : content
in the content movieclip i have various frames that i have some image , text , masks  ... like products and want to build something like slideshow !!
now i want to Create Next , Previous Button to goto next and prev frames of my content ...
i cant put my buttons in Content and i need to put these button in mc movie clip ( parent movieclip )
So  i create new Layer and in frame 1 i create 2 buttons name : nextbt and prevbt and use these script :
nextbt.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);
function fl_ClickToGoToNextFrame(event:MouseEvent):void
    content.nextFrame();
prevbt.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);
function fl_ClickToGoToNextFrame(event:MouseEvent):void
    content.prevFrame();
but now i have Problem :
i dont want to show prevbt in first frame or Nextbt in last frames of content or i want to disable it on these frames ...
thanks so much ...

Use conditionals to set the visible property based on which frame the movieclip is in.  For instance...
prevbt.visible = false;
nextbt.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);
function fl_ClickToGoToNextFrame(event:MouseEvent):void
     content.nextFrame();
     prevbt.visible = true;
     if(content.currentFrame == content.totalFrames){
        nextbt.visible = false;
prevbt.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextFrame);
function fl_ClickToGoToNextFrame(event:MouseEvent):void
    content.prevFrame();
     nextbt.visible = true;
     if(content.currentFrame == 1){
        prevbt.visible = false;
