I need your help please. I have been working on this for 2 weeks now, and I must say I understand your system much better

. I am now almost completely done with modding my forum, and tweaking everything. The adspots are one of the last few things I have to do. Here is what I have been trying to get working on the index.template.php for the adspots I was talking about going down the right and left index @ 125x125.
// Begin Ad Seller Pro Location - Right Side of the Forum 2
echo '</div>';
global $sourcedir;
include_once $sourcedir . "/adseller2.php";
$adSellerAdData = ShowAdLocation(1001);
// Check if any ads where found
if ($adSellerAdData != false)
{
echo '<div style="position:fixed; left:60px; top:800px; height:125px; width:125px">';
echo $adSellerAdData;
echo '</div>';
}
echo '</tr></table>';
// End Ad Seller Pro Location - Right Side of the Forum 2
I attached my index.template.php file.
Please help me, and teach me how I can duplicate, so I can do this for the other 30 spots on the index. I decided to go with more spots, that are smaller in size, since it makes the forum look so much better, especially on wide displays.
EDIT:BTW I know the px's are way off, but I have been messing around with the code all day trying to get it to work. The closest I got was using position:absolute , but that only worked on one sized screen, and it would stack the other ads under eachother. When I tried logging in through my Iphone for example the ad on the bottom would be way off to the right, since the Iphone screen isn't big enough it was like it wasn't even there.
I have been trying to find a way to make it stay the same no matter what size screen or browser type.
