Plugin value not saving

Hey all,

I am trying to write my first plugin but I am having trouble getting the values to save, so was wondering if someone could take a look at my code below and let me know if I am doing something wrong?

add_action('admin_menu', 'dcd_plugin_menu');
add_action('admin_init', 'dyne_office_details_options_init' );

function dyne_office_details_options_init(){
	register_setting('dyne_offices_options', 'dyne_offices_link');
}

function dcd_plugin_menu() {
	add_options_page('Dyne Drewett LLP Contact Details', 'Office Details', 8, 'dyne-contact-details', 'dyne_office_details_options_page');
}

function dyne_office_details_options_page() {
	add_option('dyne_offices_link', $offices);
?>
	<div id="howto-metaboxes-general" class="wrap">
		<?screen_icon('options-general')?>
		<h2>Dyne Drewett LLP Office Details</h2>
		<!-- Start of Left Aligned Column -->
		<form method="post" action="options.php">
			<div class="left_side">
				<?settings_fields('dyne_offices_options')?>
				<?$offices = get_option('dyne_offices_link')?>
				<?$count1 = count($offices);?>
				<!-- Offices Management -->
				<div class="metabox-holder">
					<div class="postbox">
					<h3 class="hndle"><span>Offices Management</span></h3>
						<div class="inside">
							<table class="form-table">
								<tr valign="top">
									<th scope="row">Add an office</th>
									<td><input type="text" tabindex="10" name="dyne_offices_link[<?echo $count1?>]" value="" /></td>
									<th scope="row">Current offices</th>
									<td> { Will out put the offices here }</td>
								</tr>
							</table>
						</div>
					</div>
				</div>
				<!-- End of Offices Management -->
				<!-- Submit Button -->
				<p class="submit">
					<input type="submit" tabindex="40" class="button-primary" value="<?_e('Save Changes')?>" />
				</p>
				<!-- End of Submit Button -->
			</div>
		</form>
	</div>
	<!-- End of Left Aligned Column -->
<?php
