3 JavaScript overriding each other

Hello guys, im using javascripts in my index page. For navigation hovering, slideshow and the other one is for displaying inline content in a form of a lightbox. But the problem is they cant seem to work together. i have to remove the inline content JavaScript for the slideshow and navigation hovering JavaScript to work. All of them are in the header. I want to merge all these together so that they all work. Please assist where possible. Thanks in advance

Navigation hover javascript:

[CODE]
<script type=”text/javascript”>
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf(“#”)!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}

function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf(“?”))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
</script>
[/CODE]

Slideshow Javascript:

[CODE]
<script type=”text/javascript”>

$(document).ready(function() {
$(‘#slider’).s3Slider({
timeOut: 3000
});
});
</script>

[/CODE]

Inline content Javascript:

[CODE]
<script type=”text/javascript”>
$(document).ready(function() {
$().piroBox_ext({
piro_speed : 700,
bg_alpha : 0.5,
piro_scroll : true // pirobox always positioned at the center of the page
});
});
</script>

[/CODE]
