input in theme options don't save content

Hay, I’ve got a problem with my input theme options field. When I write something, after clicking “save” option shows on the frond-end but it desappear in the dashboard. What was the cause of this?

my code in theme-options.php

<tr valign="top">
<th scope="row">
<?php _e( '4 Columns Fourth Header' ); ?>
</th>
<td><input name="ds2_theme_options[col4_4h]" type="text" value="" <?php echo $options['col4_4h']; ?> /></td>
</tr>

and I’m calling this

<article>
			<header>
				<div class="circle"><div class="ico-globe"></div></div>
				<h2><?php echo $options['col4_4h']; ?></h2>
			</header>
			<p>
			<?php echo $options['col4_4p']; ?>
			</p>
		</article>
