    include('importer_admin.php');
}

    add_options_page("OSCommerce Product Display", "OSCommerce Product Display", 1, "OSCommerce Product Display", "oscimp_admin");
}

add_action('admin_menu', 'oscimp_admin_actions');

importer_admin.php

<div class="wrap">
<?php    echo "<h2>" . __( 'OSCommerce Product Display Options', 'oscimp_trdom' ) . "</h2>"; ?>

<form name="oscimp_form" method="post" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">
    <input type="hidden" name="oscimp_hidden" value="Y">
