Theme Options Page, and IF statements…

Evening all ??
I have a theme options page, and wish to call for the following in my page:

<?php $announce = get_option('zftheme_announcement_active'); ?>
<?php if ($announce == "true"){ ?>
<a href="<?php echo stripslashes(get_option('zftheme_announcement_link')); ?>"><?php echo stripslashes(get_option('zftheme_announcement_text')); ?></a>
<? }; ?>
<?php if ($announce == "false"){ ?>
<?php echo stripslashes(get_option('zftheme_announcement_text')); ?>
<? }; ?>

So basically, if announce is true, to display it as a link, and if announce is false, then to display it as just old plain text.
Hope you understand.
Thanks in advance,
Kenneth ??
