I'm getting an erro when trying to count the number of records obtained from a mysql db. the error states:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\Program Files\Abyss Web Server\htdocs\login.php on line 6

the code is:

$db = mysql_connect("localhost", "root");
mysql_select_db("itjobhunt", $db);
$sql = "Select * FROM agency WHERE agy_ID = '" + $agy_Account + "'";
$result = mysql_query($sql);
$results = mysql_num_rows($result);
echo "<br>$results<br>";

I have an idea that this may be to do with the setup of PHP but may be completely wrong. Any idea's??

Try changing your query:

$sql = "Select * FROM agency WHERE agy_ID = '" . $agy_Account . "'";

This is what I changed.

Didn't seem to make any difference.

try adding some debug code:
$result = mysql_query($sql) or die(mysql_error());
By doing this, you may find out about errors that you might miss now...
