change text in javascript

[sun7dots]

Hi guys...

I tried to write a little script that changes a text in div element every time i put my mouse over a link... I have something like this

the script:
<script language='text/javascript'>
function zmentext(text)
{
document.all.popisek.innerHTML = text;
}
</script>

link:
zmen to

and div element:
<div ID="popisek" style='position:relative; top:0; left:40;'>huhuhuu</div>

but every time I place my mouse over the link I get object expected error... What am I doing wrong?

Thank you all for your answers

Here's what I came up with. I don't know Javascript so I kept changing things till it worked. I couldn't get it to take in a variable.

<script language="JavaScript" type="text/javascript"> 

function zmentext() 
{ 
document.all.popisek.innerHTML = "jsemtu"; 
} 
</script> 


zmen to 


<div ID="popisek" style='position:relative; top:0; left:40;'>huhuhuu</div>

edit
just got it:

<script language="JavaScript" type="text/javascript"> 
var text;

function zmentext(text) 
{ 
document.all.popisek.innerHTML = text; 
} 
</script> 


zmen to 


<div ID="popisek" style='position:relative; top:0; left:40;'>huhuhuu</div>
