Form not storing the username variable on refresh?

Hi everyone,

I am currently doing the course on how to build a wordpress plugin, all works ok but the username is not being stored.

Below is my code if you wouldn't mind taking a look and helping to spot the error that would be great.

<?php
$options = array();

function wptreehouse_badges_options_page(){

    if( !current_user_can( 'manage_options' ) ) {

        wp_die( 'You do not have sufficient permissions to access this page.' );

    }

    global $plugin_url;
    global $options;

    if( isset( $_POST['wptreehouse_form_submitted'] ) ) {

        $hidden_field = esc_html( $_POST['wptreehouse_form_submitted'] );

        if( $hidden_field == 'Y' ) {

            $wptreehouse_username = esc_html( $_POST['wptreehouse_username'] );

            $options['wptreehouse_username']  = $wptreehouse_username;
            $options['last_updated']          = time();

            update_option( 'wptreehouse-badges', $options );

        }
    }

    $options = get_option( 'wptreehouse_badges' );

    if( $options != '' ) {

        $wptreehouse_username = $options['wptreehouse_username'];

    }

    require ( 'inc/options-page-wrapper.php' );

}
?>

Here is the html form to :

                            <form name="wptreehouse_username_form" method="post" action="">

                                <input type="hidden" name="wptreehouse_form_submitted" value="Y">

                                <table class="form-table">
                                    <tr>
                                        <td><label for="wptreehouse_username">Treehouse Username</label></td>
                                        <td><input name="wptreehouse_username" id="wptreehouse_username" type="text" value="" class="regular-text" /></td>
                                    </tr>
                                </table>
                                <p>
                                    <input class="button-primary" type="submit" name="wptreehouse_username_submit" value="Save!" />
                                </p>
                            </form>

Hope you can help :)

Spotted the error of my ways,

<?php 

//Wrong Way
update_option( 'wptreehouse-badges', $options );

//Correct Way
update_option( 'wptreehouse_badges', $options );

?>
