PHP headers already sent

[ggdshpn]

Getting the following error:\[code\]"Warning: Cannot modify header information - headers already sent by (output started at..."\[/code\]for the following line:\[code\]echo '<center>Current Time is '. gmdate("H:i A") . ' GMT (Greenwich Mean Time or UTC)<br />';\[/code\]If I comment it out it just throws up the error at the next echo statement. Thoughts on why PHP hates my echo statements so much?Here is my include toward the bottom of the HTML:\[code\]<div id="saveCanForm" width="100%"><?php include('savereport.php'); ?></div>\[/code\]
