Help with code

I need to remove all “sound”“sonido”“suena” code from it and keep the scrolling for the text.
It happened that when I added sound to a different swf… when I press on the text buttoms to scroll… music stops. In order to avoid this and with the fact that Im not using the sound on these buttoms anyway… I’ve beign trying to adjust the code but…

In case this is not clear… I can approach it differently…
I want the code to be adjusted on the way that the buttoms subir=up and bajar=down will scroll up and down the XML text included in this.

Thanks

Stage.scaleMode = “noScale”;
// –
sonidoScroll = new Sound();
sonidoScroll.attachSound(“sonido”);
sonidoScroll.setVolume(50);
// –
this.createEmptyMovieClip(“loop”, this.getNextHighestDepth());
// –
stopScroll = function () { sonidoScroll.stop();delete loop.onEnterFrame;this.texto.textColor = 0x000000;suena = undefined;};
// –
startScroll = function (texto, direccion) { loop.onEnterFrame = function() {if (texto.scroll == texto.maxscroll && direccion == 1 || texto.scroll == 1 && direccion<1) {sonidoScroll.stop();} else {if (!suena) {sonidoScroll.start(0, 999);suena = true;}}texto.scroll += direccion;};};
subir_btn.onRollOver = function() {
this.texto.textColor = 0xff0000;
startScroll(content, 1);
};
bajar_btn.onRollOver = function() {
this.texto.textColor = 0xff0000;
startScroll(content, -1);
};

subir_btn.onRollOut = bajar_btn.onRollOut=stopScroll;
