salve a tutti!
Ho trovato uno script Java per far muove qualunque div seguendo lo scrolling. Ho fatto delle prove con delle immagini all'interno dei div per verificare la funzionabilità e ho constatato che funziona però quando lo inserisco nella pagina che sto costruendo non mi funziona, credo sia un problema di posizione dei div, forse devo cambiare i css ...

Questi sono gli script:

<head>
<style type="text/css">

a img {
border:none;
}


.main{
float:left;
height:1000px;
width:799px;
}

.nav {background-color:#f7fafc;
float:left;
height:980px;
width:230px;
border-left-style:solid;
border-left-color:#b1d4f9;
border-left-width:1px;
border-right-style:solid;
border-right-color:#b1d4f9;
border-right-width:1px;
margin-left:1px
}

.cella {background-color:#97efd3;
width:175px;
-moz-border-radius: 10px 30px;
border-radius: 10px 30px / 15px 25px;
padding:10px;
border:1px ;
border-style:solid;
border-color:#178a7a;
margin:10px;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 11px;
font-weight: bold;
text-decoration: none;
text-align: center;
}



.menuelementi a {color: #330099;
width: 150px;
background-color: 97efd3;
padding: 2px;
padding-left: 3px;
border-bottom: 1px solid #b1d4f9;
font-family: 'URW Chancery L Medium Italic', Verdana, Arial, Helvetica, sans-serif;
font-size: 11px;
font-weight: bold;
text-decoration: none;
text-align: left;}


.cartina{background-color:#f7fafc;
float: right;
height:980px;
width:546px;
border-left-style:solid;
border-left-color:#b1d4f9;
border-left-width:1px;
border-right-style:solid;
border-right-color:#b1d4f9;
border-right-width:1px;
}

.boxdestro{
float:right;
height:640px;
width:140px;
}

</style>


<script type="text/javascript">
var verticalpos="frombottom"

function JSFX_FloatTopDiv()
{
var startX = 5,

if (verticalpos=="fromtop")

else{

return el;
