N 6.2 and position absolute top and percentage values

Hello,

I have a question on Netscape 6.2 (6.x?). I use CSS and divs for
positioning different elements, but N6.2 doesn´t do the right thing.
N6.2 ignores the percentage values, but not e.g. px-values. Because N6.2
ignores the top-percentage-value (at #Spieltag) the div-element is not
where it should be. It works fine in N7 and IE6. Any idea what's causing
that?

Thanks for help

Code looks like this:

<div id="roundDataXml">
...some content...
<div id="SpielTab">
...table...
</div>
</div>


#SpielTab {
position:absolute;
top:102%; // this value is ignored if applied as %
left:21%;
right:21%;
}

#roundDataXml {
position:absolute;
left:19%;
top:52%;
}
