Parse error:syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ‘,’ or ‘;’ in /home/content/39/7897939/html/wp-content/plugins/db-toolkit/data_report/templatemode.php(453) : eval()’d code on line 11

I know the error occurs in this segment of code, because if I remove this segment, the error goes away. CANNOT find what it might be!!

Code:
<?php 
	$caresheetlink = '{{caresheetlink}}'; 
	$gallerylink = '{{gallerylink}}'; 
	if ((!empty($caresheetlink)) && (!empty($gallerylink))) {
		echo '<div class="sp-btn-first"><span class="spbutton"><div class="sp-button" onClick="parent.location='{{caresheetlink}}'"><span>Care Sheet</span></div></span></div><div class="sp-btn"><span class="spbutton"><div class="sp-button" onClick="parent.location='{{gallerylink}}'"><span>Photo Gallery</span></div></span></div>';
	}
?>
