this is what you have (using Brad's suggestion, I will use the [ PHP ] tags:
<?php
$vew_page_content .= "<center><object classid=\"clsid27CDB6E-AE6D-11cf-96B8-444553540000\"<a href="http:www.seattleperforms.com/ltw\" target=\"_blank\"><img src="../images/ltw_2007/TPS_LTW-Flash-Top-Hat.gif" width="770" height="240" border="0" /></a>";
?>
As you can see, you escape the first and second double-quotes, but not the next one(s).
So, try:
<?php
$vew_page_content .= "<center><object classid=\"clsid27CDB6E-AE6D-11cf-96B8-444553540000\"<a href=\"http:www.seattleperforms.com/ltw\" target=\"_blank\"><img src=\"../images/ltw_2007/TPS_LTW-Flash-Top-Hat.gif\" width=\"770\" height=\"240\" border=\"0\" /></a>";
?>
But, it is much, much easier to use single quotes in these cases me thinks.
Or try this:
<?php
$vew_page_content .= '<center><object classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000"<a href="http:www.seattleperforms.com/ltw" target="_blank"><img src="../images/ltw_2007/TPS_LTW-Flash-Top-Hat.gif" width="770" height="240" border="0" /></a>';
?>
