Shouldn't you use echo instead of "=" ?

ie: replace
<TD><?=$server[$i]->m_servervars["serveraddress"]; ?></TD>
with

<TD><? echo $server[$i]->m_servervars["serveraddress"]; ?></TD>

In this row you have several columns starting "<?="

What is that equal sign there for?

That's probably causing the error.
