Changing 'Read More' Button

I’ve recently installed a new theme and have been trying to alter some of the design features on the front page.

I have the most up to date posts, listed under a feature box, each with a read more button next to them by default.

I want to change this ‘Read More’ text to something else but am having great difficulty attempting it.

I’ve tried playing around with this code I have found

[please use the code button to mark any posted code – the sections below are broken]

<?php if($theme->display(‘read_more’)) { ?>
<div class=”readmore”>
#more-<?php the_ID(); ?>” title=”<?php printf( esc_attr__( ‘Permalink to %s’, ‘themater’ ), the_title_attribute( ‘echo=0’ ) ); ?>” rel=”bookmark”><?php $theme->option(‘read_more’); ?>
</div>
<?php } ?>

But as soon as I altered it to what I thought was right, which was this:

[please use the code button to mark any posted code – the sections below are broken]

<?php if($theme->display(‘get_it’)) { ?>
<div class=”readmore”>
#more-<?php the_ID(); ?>” title=”<?php printf( esc_attr__( ‘Permalink to %s’, ‘themater’ ), the_title_attribute( ‘echo=0’ ) ); ?>” rel=”bookmark”><?php $theme->option(‘get_it’); ?>
</div>
<?php } ?>

It disappeared. Any ideas?
