Look closely at this bit: '</b></td>><td>'
Never to worry, I've lost staring-contests with my HTML too. ;)
Tip:
You could use more line breaks and indentation, and when you output literal HTML
code, do it directly instead of using print statements where possible. Both of
these methods make the code more readable especially if you have syntax-coloring
in the editor. Errors are far easier to see.
For example:
<body>
<table border="1" align="center">
<tr>
<td colspan="2" align="center">
<b><?=$title?></b>
</td>
</tr>
<?php
foreach ($fields as $field) {
$fieldValue[$field] = $_POST[$field];
?>
<tr>
<td>
<b><?=$fieldDisplay[$i]?></b>
</td>
<td>
<?=$fieldValue[$field]?>
</td>
</tr>
<?php
$i++;
}
</table>
</body>
