How do i remove the pop-up ads in this script?

Ok so it seems like someone stuck pop-up ads in this script before i started messing with it, how do i remove the pop-up ads, i do not care about the normal banner ads on the site.

You have some JS you need to remove

<SCRIPT LANGUAGE="JavaScript"> 
<!--
function popitup(url) {
	newwindow=window.open(url,'name','height=250,width=400');
	if (window.focus) {newwindow.focus()}
	return false;
}
 
function popitup2(url) {
	newwindow=window.open(url,'name','height=350,width=550');
	if (window.focus) {newwindow.focus()}
	return false;
}
 
function popitup3(url) {
	newwindow=window.open(url,'name','height=1,width=1');
	if (window.focus) {newwindow.focus()}
	return false;
}
 
// -->
</script>

Code (markup):

 

Well that will cause the script to stop functioning correctly, since i need that code so that users can launch the music player or watch videos
