On the main timeline, layer as, I have the function goPage:

```auto
_root.C.anterior._visible=0;
function goPage (whichWay) {
	_root.content.destinationFrame = _root.content._currentFrame+whichWay;
	_root.content.alphaChange = -20;
	_root.C.proximo._visible=(_root.content.destinationFrame<>1);
	_root.C.anterior._visible=(_root.content.destinationFrame<>_root.content._totalFrames);
	//trace("function goPage OK");
	updateAfterEvent;
}

```

On a movieclip (instance name “content”) I set:

```auto
onClipEvent(load) {
	stop();
	
}

onClipEvent(enterFrame) {
	_root.C.frameatual = "( " + _root.content._currentframe;
	_root.C.framestotal = "/ " + _root.content._totalframes + " )";
	_alpha+=alphaChange;
	if(_alpha<1) {
		gotoAndStop(destinationFrame);
		alphaChange=20;
	_root.C.frameatual = "( " + _root.content._currentframe;
	_root.C.framestotal = "/ " + _root.content._totalframes + " )";
	}
	if(_alpha>100) {
		alphaChange=0;
	}
}

```

on the btn “next” I set:

```auto
_root.goPage(+1);

```

on the “previous” btn:

```auto
_root.goPage(-1);

```

[color=red] When I hit the next btn the content does not go to the next frame. It goes to the last one. I used this actions in another work and it works fine. What is happening here?[/color]

Thanks

Well, Im not sure, but you are sending “+1” to the goPage-function as a parameter.

Then, in goPage, you are adding “+1” to currentFrame, resulting in the expression:

currentFrame + +1

I mean, if you send “-1” that is a number (minus one), but if you are sending “+1” that is an expression (ADD one - not a simple one).

Try just sending “1” in the goPage-next call, and leave the “-1” in the goPage-previous call, and perhaps it will work.

I tried that but it doesnt work!  
I think it might be something with the swf that is loaded into the movieclip.  
Its has some layers with text, mcs, fotos, like a page of a book. And there are some actions and empty movieclips. Sometimes I think its misunderstanding something and cant go to the next frame stooping at the last one.  
Thanks for helping!!!  
Comeback if I find something else.

try

function goPage (whichWay) {
        _root.content.destinationFrame = _root.content._currentFrame+Number(whichWay);
        _root.content.alphaChange = -20;
        _root.C.proximo._visible=(_root.content.destinationFrame<>1);
        _root.C.anterior._visible=(_root.content.destinationFrame<>_root.content._totalFrames);
        //trace("function goPage OK");
        updateAfterEvent;

one quick thing I noticed skimming

updateAfterEvent;

should be

updateAfterEvent();
