Hi

I am building a website on wamp that I can play around with and have got some errors

They are

SCREAM: Error suppression ignored for
( ! ) Notice: Undefined index: qs in C:\wamp\www\admin website\admin\index.php on line 22

AND

SCREAM: Error suppression ignored for
( ! ) Notice: Undefined index: inv_usr in C:\wamp\www\admin website\admin\index.php on line 52

ON LINE 22 IS THE FOLLOWING

if($_REQUEST["qs"]=="logout"

AND ON LINE 52 IS THE FOLLOWING

<?php if($_GET['inv_usr'] == 'yes')

I got a couple on the front end of the website as well but will worry about them after

Any ideas

Kind regards

Ian
