Can anyone help me please?

Hi!

Good Day guys!

i have these two wml pages...
browse.php and cat.php

BROWSE.PHP

<?php
include "include/wml.inc";
include "config.php";
?>
<card id="index" title="Select Type">
<p align="center" mode="wrap">Welcome
<br/>
<br/>
</p>
<p align="left" mode="wrap">Type of building:
<select name="category">
<?php
$sql = "SELECT DISTINCT category FROM $tname ORDER BY category ASC";
$query = mysql_db_query($dname,$sql,$my_conn);
?>
<?php
while ($row = mysql_fetch_array($query))
{
echo "<option value=\"$row[category]\">";
echo ucwords($row[category]);
echo "</option>";
}
?>
</select>
<anchor>Submit
<go href="cat.php" method="get">
<postfield name="category" value="$category"/>
</go>
</anchor>
</p>
</card>
</wml>

CAT.PHP

<?php
include "include/wml.inc";
include "config.php";
?>
<?php
$cat_search = $category;
?>
<card id="index" title="Select Type">
<p align="center" mode="wrap">Welcome
<br/>
<br/>
Type of building: <b><?php echo ucwords($cat_search) ?></b>
</p>
<p align="left" mode="wrap">Choose a building
<select name="building">
<?php
$sql = "SELECT * FROM $tname WHERE category = '$cat_search' ORDER BY category ASC";
$query = mysql_db_query($dname,$sql,$my_conn);
?>
<?php
while ($row = mysql_fetch_array($query))
{
echo "<option value=\"$row[place]\">";
echo ucwords(strtolower($row[place]));
echo "</option>";
}
?>
</select>
<anchor>Submit
<go href="build.php" method="get">
<postfield name="building" value="$building"/>
</go>
</anchor>
</p>
</card>
</wml>

Problem is CAT.PHP errors with "NO GATEWAY REPLY"
i only created CAT.PHP with editing the SQL for BROWSE.PHP and some formatting...
tnx guys!

Mulitple questions , number one probably most important.

Does include/wml.inc contain wml header information?
Is it definately included as requried?
Do you have error reporting on - if you do your pages will fail as your php is badly written - reporting syntax would maybe cause the page not to be formed correctly.
Is legit syntax - it may well be, just never seen it before. If it isn't, then page will fail.

Also please read the sticky on how to post a question. Use [php.]tags (no .), and use useful subject lines - many people would ignore a subject line like yours.
