in reply to accessing values in hash

You didn't provide enough information for anyone to give you any meaningful assistance.

Obviously, check to see if everything is defined and the database request didn't return an error (such as "item not found").

    hi there, there is no problem accessing the database. I am using; 
    $sth = $dbh->prepare("select username, password from reg");

$sth->execute;

    and then the previous code I have posted to fetch and display it. But I need to print out whether the username i have it $testUsername matches one of the usernames returned from the database

        sorry I have never came across grep. You mean I should be looking to do something like: 
        
$sth = $dbh->prepare(q{select username, password from reg 

where username = ?});

$sth->execute($testUsername);
