adding a simple php include breaks archives, categories, and links

Hi,

I’m using StarSol’s Random Quote script (http://www.starsol.co.uk/scripts/scripts.php).

When I add a simple php include call to it:
<?php include “../quotes/quotation.php”; ?>
The quote is included as expected but Archives has no links and Categories now says “no categories” in the sidebar.

Strangely, I remove my include line, and the categories, archives and links are working again in the sidebar. What could be causing this?

The quotes script is a simple database query with an “echo” statement at the end that outputs the quote. For example, you can load this page over and over and it works:
http://nimbleswitch.com/quotes/quotation.php

but trying to include it in php causes some serious havoc.
Any ideas?

PS the code for the quotation script looks like this:

<?php

require (‘quotation_includes.php’);

connect_to_mysql();

$how_many = mysql_num_rows(mysql_query(“SELECT quotation FROM “.$db_prefix.”quotations”));
$how_many_minus_one = $how_many – 1;

$random = rand(0,$how_many_minus_one);

$rq = mysql_fetch_array(mysql_query(“SELECT quotation FROM “.$db_prefix.”quotations LIMIT “.$random.”, 1″));

$rq[quotation] = nl2br($rq[quotation]);

mysql_close();

echo $rq[quotation];

?>
