Mouseover for mobil devices?

ok, thank you. Do you have an example how i change the button?

currently it is like this:

var _this = this;
var frameNumber;
/*
Durch Bewegen der Maus über die angegebene Symbolinstanz wird eine Funktion ausgeführt.
'3' gibt an, wie oft das Ereignis ausgelöst werden soll.
*/
/*stage.enableMouseOver(3);
_this.info_1.on('mouseover', function(){
/*
Verschiebt den Abspielkopf in der Zeitleiste zur angegebenen Bildnummer und setzt die Wiedergabe ab diesem Bild fort.
Kann in der Hauptzeitleiste oder in Movieclip-Zeitleisten verwendet werden.

_this.gotoAndPlay(411);
});*/

/* Mouse Over Event
Mousing over the symbol instance executes a function in which you can add your own custom code.

Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the symbol instance is moused over.
frequency is the number of the times event should be triggered.
*/
var frequency = 1;
stage.enableMouseOver(frequency);
this.info_1.addEventListener("mouseover", fl_MouseOverHandler);

function fl_MouseOverHandler()
{
frameNumber = this.currentFrame;
// Start your custom code
// This example code displays the words "Moused over" in the Output panel.
_this.gotoAndPlay(411);
// End your custom code
}

/* Mouse Out Event
Mousing out of the symbol instance executes a function in which you can add your own custom code.

*/
//var frequency = 2;
stage.enableMouseOver(2);
this.info_1.addEventListener("mouseout", fl_MouseOutHandler);

function fl_MouseOutHandler()
{
if (frameNumber > 159)
{
_this.gotoAndPlay(275);
}
else{
_this.gotoAndPlay(159);
}
// Start your custom code

//_this.gotoAndPlay(frameNumber);
