I'm trying to increase the notice period for calendar email event reminders from the VB current max of 3 days to 7 and 14 days.

Can't work out how to do it

So far I've altered templates calender reminder choose type and calendar reminder with new option values of 604800 and 1209600 and new phrase of seven_days and fourteen_days which i've defined in phrase manager so this lets me select the 7 and 14 day option.

in includes/function_calendar.php I've added to but still can't get the new reminders to work.

Can anyone tell me what to do next please??

TIA
