Adding another midrow block to Zenon Light?

Hi, I have the Zenon Light theme installed, but would like to add another midrow block to my theme. Zenon Light itself has 4, but I want 5.

I’ve added the following into the options.php

$options[] = array( "name" => __('Block 5 Heading', 'zenon'),
						"desc" => "",
						"id" => "block5_text",
						"std" => "Block 5 Heading",
						"type" => "text");

	$options[] = array( "name" => __('Block 5 Text', 'zenon'),
						"desc" => "",
						"id" => "block4_textarea",
						"std" => "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam nec rhoncus risus. In ultrices lacinia ipsum.",
						"type" => "textarea");

And the following into the index.php:

<?php if ( of_get_option('block5_textarea') ) { ?>
        <div class="midrow_block">
        <div class="mid_block_content">
        <h3><?php echo of_get_option('block5_text'); ?></h3>
        <p><?php echo of_get_option('block5_textarea'); ?></p>
        </div>
        </div>
        <?php } ?>

But I’m not sure why the other block isn’t showing up. Thanks!
