I think the inventory script was for 1.1.X and I think you're using 1.2.0
And the furthest editing I got for the inventory script was:

<?php

include("inc/functions.php");
include("inc/config.php");

//***************//
//  START SCRIPT //
//***************//

$themeurl = grabanysetting("themeurl");
$links = getlinks();
$ads = getads("any");
$pagecontent = getsitecontent("index");
$article_title = $pagecontent[title];
$article_content = $pagecontent[content];
$article_content = nl2br($article_content);

$article_title = "Your Inventory";

if ($isloggedin == "yes") {
$article_content = "Here you can see a list of items that you have collected.<table width='500' border='2'>
<tr>
    <td width='200'><strong>Picture:</strong></td>
    <td width='230'><strong>Item Type: </strong></td>
    <td width='70'><strong>ID Number:</strong></td>
</tr>";
 
$query = "SELECT * FROM ".$prefix."useritems WHERE Owner = '$loggedinname'";
$result = mysql_query($query);
$num = mysql_numrows($result);

$i=0;
while ($i < $num) {

$iid=@mysql_result($result,$i,"ID");
$object=@mysql_result($result,$i,"Item");
$url=@mysql_result($result,$i,"imageurl");


$article_content = $article_content."<tr>
    <td><center><img src='".$url."'></center></td>
    <td><center>".$object."</center></td>
    <td><center>".$iid."</center></td>
  </tr>";

unset($iid);
unset($object);

$i = $i + 1;
}
$article_content = $article_content."</table>";

}
else {

$article_content = "You must be logged in to view items.";

}
//***************//
//  OUTPUT PAGE  //
//***************//

echo showpage($article_title, $article_content, $date);

?>

I couldn't continue because I have no idea how to insert a new table, and it's required to insert a table which is:

id, int(11), not null, auto_increment 
owner, varchar(40), latin1_general_ci, yes (NULL)	
itemtype, varchar(40), latin1_general_ci, yes (NULL)
imgurl, varchar(120), latin1_general_ci, yes (NULL)

But yeah :P
