The error occurs because you did not initialize the $filter and $filterfield

variables before using them; this does not indicate an error because these 
variables will most likely not be set when the form is displayed initially.

You have multiple options to avoid this error:

1) Change the error_reporting setting in your php.ini or set 
"error_reporting (E_ALL & ~(E_STRICT|E_NOTICE));" inside your php script.
>> This disables PHP notices but could make debugging a bit more
complicated.

2) Initialize the variables before using them:
[CODE]
// I assume the variables will be passed by the form, that's why they are in
the 
// superglobal $_POST array; if the variable has been passed (isset(...),
use it,
// otherwise initialize with false

$filter = isset($_POST["filter"]) ? $_POST["filter"] : false;
$filterfield = isset($_POST["filterfield"]) ? $_POST["filterfield"] : false;
[/CODE]

HTH!

Regards,

Sascha
