Hello. I'm relatively new to PHP and can't figure out what's wrong.

       function tweet_button () {
        echo '
<div class="twitter-share vcount"> 
<a class="twitter-button" rel="external nofollow" title="Share this article on Twitter" href="http://twitter.com/share?text=<?php echo $shareTitle; ?>+-&amp;url=<?php echo $shareUrl; ?>
&amp;via=<?php if (!$retweetNick == '') { echo $retweetNick; } ?>
&amp;related=<?php if (!$retweetrelate == ''){ echo $retweetrelate; } ?>:<?php if (!$retweetrelate == '') { echo $retweetrelatedesc; } ?>" target="_blank">Tweet this article</a> 
<span class="twitter-count"><?php echo $retweetInfo; ?></span></div>
';

This was part of the code of a WordPress plugin I'm trying to make and when I try to activate the plugin, it gives me

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in C:\xampp\htdocs\wordpress\wp-content\plugins\sample-plugin\sample-plugin.php on line 51

Line 51 is the line that starts with &amp;related=

Hello fellow phpfeaks,

I have been working on debugging this script for hours. I am getting this error message: Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/heartl20/public_html/sendmail.php on line 58
Here is the php portion of the code with line 58 identified. I don't think that line 58 is really the offender but something in the code is. Your help for this php newbie is much appreciated. Also any suggestions on making this script better would be appreciated also.
