[RESOLVED] Why doesn't this query work

[dugindog]

CREATE TABLE `testt` ( `lname` varchar(250) NOT NULL default '', `email` varchar(250) NOT NULL default '',`ukey` int(11) NOT NULL auto_increment, PRIMARY KEY (`ukey`) `ukey` int(11) NOT NULL auto_increment);

basically the page this is displayed on attempts to create this table create in a generic format, however the final string does not seem to be liked when I try and run the query.

the error is:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ukey` int(11) NOT NULL auto_increment,)' at line 1

here is the php code I'm using:

<?php

// Database variables



$dbserver = "localhost";  //Server hosting the database
$database = "";  //place name of database here
$username = "";  //database username here
$password = "";  //database users password here
$tablename = "";  //database table name associated with this form


$dbh=mysql_connect ($dbserver, $username , $password) or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ($database) or die ('I cannot connect to the database because: ' . mysql_error());


$tqr = "CREATE TABLE `$tablename` (";
if (!empty($_REQUEST)) { 
    foreach ($_REQUEST as $k=>$v) { 
        ${$k} = $v; 
        echo "$k = '$v'<BR>";

    if ($t != $k) {
    $tqr .= " `$k` varchar(250) NOT NULL default '',";
    }
    $t = $k;
}
} 
$tqr .= "`ukey` int(11) NOT NULL auto_increment, PRIMARY KEY (`ukey`) `ukey` int(11) NOT NULL auto_increment,);";

$sql = 'CREATE TABLE `orders` (' . ' `lname` varchar(250) NOT NULL default \'\','
        . ' `email` varchar(250) NOT NULL default \'\','
        . ' `ukey` int(11) NOT NULL auto_increment,'
        . ' PRIMARY KEY (`ukey`)'
        . ' `ukey` int(11) NOT NULL auto_increment,)';


echo $sql . "<HR>" . $tqr . "<BR><BR>";
mysql_query($tqr,$dbh) or die('I cannot create the table because: ' . mysql_error());

if (mysql_query($tqr,$dbh)) {
	echo "Successfully created table `orders`";
}
