spinner control and using number to activate href to bookmark

Hi All. I desperately need help with Javascript.
Problem. I have quite an advanced spinner program. It was obtained here: Javascript Controls - The Spin Control | Switch on the Code

I am trying to get a spinner button (which selects from 6 - 30 [but customizable] numbers to update a variable and then for this variable to update a href link to a bookmark.

What I have so far.

1. SPINNER CODE on web page. NB the javascript code this refers to is not shown

HTML Code:

</head>
<body>
<script type="text/javascript">
var spinCtrl = new SpinControl();
spinCtrl.GetAccelerationCollection().Add(new SpinControlAcceleration(1, 300));
document.body.appendChild(spinCtrl.GetContainer());
spinCtrl.StartListening();
spinCtrl.Tag = 'left';
spinCtrl.SetMaxValue(30);
spinCtrl.SetMinValue(6);
spinCtrl.GetContainer().style.position = 'absolute';
spinCtrl.GetContainer().style.left = '15px';
spinCtrl.GetContainer().style.top = '10px';
spinCtrl.AttachValueChangedListener(spinCtrlPrintOut);
spinCtrl.AttachValueChangedListener(spinCtrlSizeBox);
spinCtrl.AttachValueChangedListener(spinner);  --->I added this
spinCtrl.SetCurrentValue(6);
</script>

The HREF link:

HTML Code:

<a href="example.html" id ="name" onclick="location.href=this.href+'#'+link;return false;">Link</a>

going to a bookmark here: <a name="8">

AND my spinner function: PLEEZE note that ths is where the wheels come off.
I want the newVal variable in the functon [which containts the current spin number] to be put into a variable and then for the variable to be sent outside the function to "link" in HREF above. i.e. this way the HREF code can place in the #8and it will jump to the bookmark.

HTML Code:

 <script type="text/javascript">
function spinner(sender, newVal)
{
var hold = newVal;
var id = 'name' 
window.link = hold;
}
</script>

NOTE that a variable var link = 8; declared outside the function (globally) works perfectly.
But I simply cannot see how to get access to the newVar variable i.e. current spinner position within this function :

Code:

 function spinner(sender, newVal)
{
var hold = newVal;
var id = 'name' 
window.link = hold;
}

Anyone who knows how to do this will be blessed in my eyes. PS I am also a beginner programmer so may simply be missing a simple boat.

Kind regards

I was up all night and sorted it out.

It seems to be working..... well I will still need to bug test a bit.
