Quick question. Strange problem?

[spires]

Hi,

I have built a loging system, This works fine.
You type in your details, Which POSTs the values back to the same page, checks to see if there in the database, then it registers the sessions and (using a header) sends you to the next page.

However, if i do any php selecting from the database below the form, the sessions DO NOT register.

Has anyone ever seen this before?
If so, why does it do this?

Here is an example of what i mean.
The top section pulls the info out of the database.
This only works if its above the form.
If i use it below the form (Where the variables are) It dont work.
[code]
<?php
$cstyle_query = mysql_query("SELECT * FROM choosen_style") or die (mysql_error());
$cstyle_row = mysql_fetch_array($cstyle_query);
$cstyle_id = $cstyle_row['csty_id'];

$style_query = mysql_query("SELECT * FROM styles WHERE sty_id='$cstyle_id'") or die (mysql_error());
$style_row = mysql_fetch_array($style_query);
$style_id = $style_row['sty_id'];
$foot = $style_row['foot'];
$pole2 = $style_row['pole2'];
?>

It should be fine, so what error occurs when you try this?
