Structure vs content prob

Hi
at the moment I am running into difficulties trying to define a loading area of a page, in relation to its structure. For example I want all pages to load into a specific table of structure.php. it does not like this psuedo function that I have created. is there a more practical way of achieving this??

This is Structure.php

[COLOR=Indigo]<body>

<table width=“774” border=“0” cellpadding=“0” cellspacing=“0”>
<!–DWLayoutTable–>
<tr>
<td width=“340” rowspan=“3” valign=“top”><table width=“100%” border=“0” cellpadding=“0” cellspacing=“0”>
<!–DWLayoutTable–>
<tr>
<td width=“23” height=“40”> </td>
<td width=“317”> </td>
</tr>
<tr>
<td height=“105” colspan=“2” valign=“top”><p>gooooooooooooooooooooooooooooooooooooo</p>
<p>gooooooooooooooooooooooooooooooooooooooooo</p>
<p>goooooooooooooooooooooooooooooooooooooo</p></td>
</tr>
<tr>
<td height=“49”> </td>
<td> </td>
</tr>
<tr>
<td height=“404”> </td>
<td valign=“top”><img src=“8486-b.jpg” width=“430” height=“394”></td>
</tr>
<tr>
<td height=“144”> </td>
<td> </td>
</tr>
</table></td>
<td width=“53” height=“47”> </td>
<td width=“381”> </td>
</tr>
<tr>
<td height=“294”> </td>
<td valign=“top”>
<?php
function _text()
?>
</td>
</tr>
<tr>
<td height=“401”> </td>
<td> </td>
</tr>
<tr>
<td height=“645”> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
[/COLOR]

this is go.php

[COLOR=Green]<?
require (“structure.php”);
?>
<p><img src=“mermap.jpg” width=“568” height=“321”></p>
<?php
_text()
?>
[/COLOR]

go.php should load into the area of structure using <?php
function _text()
?>
