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());

Have you tested this SQL query?
Insert it into phpmyadmin, does it work?

If it does => php error.
If it doesn't => mysql error.

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.

The quotes are OK.

Tested - works.

Try putting single quotes around $timebegin. If $timebegin is not a
Unix timestamp, you can also use the DATE functions in MySQL,

A good way to debug these problems is to always put the query in a
separate variable

$query = "SELECT * FROM messages ..."
//echo $query;
//exit;
$laterrecords = mysql_query($query);

Then echo the actual interpolated query to the screen, copy it, and
run it manually in a query tool (phpMyAdmin,
MySQLQueryBrowser, or similar).

The query tool will tell you where the error is.
