Hoover Buttons & PHP

I am trying to get hover, or rollover buttons to work.  I want to swap between two images when the mouse goes over the button.  I have no trouble in HTML but cant get it to work when I put it in my PHP code.  

The last thing I tried was to enclose the java call between print <<< HERE like so:

print <<<HERE
      <table width="800" border="0" align="center" cellpadding="0">
<tr><td align="center"><a href="#tp" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('back-to-top','','buttons/back_top.jpg',1)"><img src="buttons/back_top_on.jpg" name="back-to-top" width="101" height="27" border="0"></a></p>
</td></tr></table>
HERE;

I also tried jumping in and out of PHP and printing them in the code by print '...   ....';

Here is the java code generated by DreamWeaver:

<script language="JavaScript" 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>
