Your variable is not in scope. Either pass your variable as a
reference in the function definition:
function RatingFilter (&$sql) {
...
}

or use the global keyword to bring your variable into scope:
function RatingFilter () {
global $sql;
if ($br) {$sql.= " and beg_rate >= '2'";}
...
}

And follow the advice of Charles and read up on it so you know
how they are different.
