hi, im doing a little test to check whether the user is "away" (unactive) or not;

function away_status(){
    $("#away_stat_update").everyTime(1000, function(i) { 
        var number = Number($(this).html());
        if( number == 20 ) {
            // set user as away 
            alert( "user away" );
        }
        if( number > 20 ) {
            $("*").mousemove(function(e){
                $("#away_stat_update").html(0);
                var number = Number(0);
                // reset user to being online
                alert( "user back online" );
            });
        }
        $("#away_stat_update").html( number + 1 );
    });
    $("*").mousemove(function(e){
        $("#away_stat_update").html(0);
    });
}
away_status();

the only problem is that when the number is greater than 20 and the mouse is moved it keeps alerting "user back on line" instead of doing it just once. The number is resetting by the way.
