Need someone to trouble shoot this script error

Hi

I am making the administration area for a product catalog. To add a product a person will select a category fro a list which will be pulled from the database. However, there is something going wrong which i am not able to understand. Any help would be appreciated. Heres the relevant part of the code.

<?
$title=Add Prdocut;
include("../connect.inc");
include("templates/header.inc"); ?>

<?
function build_category_tree(&$output, $parent=0, $indent="") 
{

    $qid = mysql_query("SELECT id, name FROM categories WHERE parent_id = $parent");
    while ($cat =  mysql_fetch_array($qid)) {
        $output .= "<option value='$cat["id"]'>$indent" . $cat["name"];
        if ($cat["id"] != $parent) {
            build_category_tree($output, $cat["id"], $indent."&nbsp;&nbsp;");
        }
    }
}
?>

Category
Category: <SELECT NAME="sizeid" SIZE=1>
  <OPTION SELECTED VALUE="" >Select Category
  <OPTION VALUE="">---------
<?php
$output="";
build_category_tree($output);
echo($output);

<? include("templates/footer.inc") ?>

the header and the footer just contain the html formatting and the connect.inc has the information to connect to the database.

Heres the error I am getting from the browser on running the script.

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in c:\apache\htdocs\surplusgemstones\admin\test.php on line 12

I have no idea what that means.
Thanks for the help in advance.

It's because you have $cat["id"] inside of your .= "...". You can do $cat[id] or concat it into the string like you did for $cat["name"].

Thanks for pointing that out. But still there is some error in the code. Now the browser is pointing the error to line 29 which is where I am calling the function.

I am sure it is something basic but I am new to php.

Thanks for the help.

Take out the <? before you include the footer.
