Well, seems to me like a problem with quotes you're using in query...
The ` quotes you're using doesn't work, when I tried to use them in PHP
called query. Maybe you should try use single quotes and if they works.
I need help to track down the cause of the error,"Could not run query"
A typical query is
$laterrecords = mysql_query("SELECT * FROM messages WHERE `logged` >
$timebegin ORDER BY `logged` DESC" ) or die ("Cannot
select:<br>$query<br>Error: " . mysql_error());
