Does anyone know how I can set the increment speed of script below? I want to be able to slow down the speed of i++ and i--.

<script language="javascript">
function down()
{
for (i=30;i<=200;i++) {
document.getElementById('bob').style.top=(i);
}
}
function up()
{
for (i=200;i>=30;i--) {
document.getElementById('bob').style.top=(i);
}
}
</script>
</head>
<body>

<a href="javascript://" onclick="down()">Down</a> | <a href="javascript://" onclick="up()">Up</a>

<div id="bob" style="width:200;height:200;border:solid 1px black;position:absolute;top:30;background:silver"></div>

Any input would be great - Thanks

Try setInterval()? I used that for a fade script here (http://jsg.byethost4.com/fade+IE.html).

Arbitrator - I tried setInterval; before I posted this script, but I could never get it to work the right way. I think I put setInterval in the wrong place or I did not implement it right. Do you know how I can apply setInterval to my script and make it delay the i++ and i-- increment speed?
