Salve

ho scaricato il clandario eventi da html.it
event_calendar

installandolo mi da questo errore

Notice: Use of undefined constant event_ - assumed 'event_' in event_calendar.php on line 56
Notice: Use of undefined constant event_ - assumed 'event_' in event_calendar.php on line 60

ma sapendone mezza di php... non capisco...

ecco il codice a partire dalla riga 56

    if(${event_.$day} == "") {
    $event_display = "There are no events for today.";
    }
    else {
    $event_display = ${event_.$day};
    } 

...di che tipo di errore si tratta?


e di seguito.... tutto il codice
