mysql_query troubles

Hi all', I have a mysql_query that reads: $testResult = mysql_query("SELECT * FROM login_table where Pass = password('$password')") or die ("ouch"); $num_rows = mysql_num_rows($testResult); the problem is that I keep getting a value of 0 for $num_rows when I know the table has 1 entry for PAss which equals password('$password'). The password I have used is just 'a' (before pasing throught the password function in the insert). I DO have a table named login_table I KNOW that there is an entry that matches 'password('$password)'.. ( i checked using phpMyAdmin) can anyone help?????? Thanks in advance, brad
