Can't edit events in Calendar
I'm an iPad newbie here. Just got one yesterday and was playing with it the whole night last night. Everything is nice except for the problem that the Calendar app won't let me edit any event in the calendar. My ipad Calendar is synced with my Google calendar, which is also synced with the iCal on my Macbook. For some reason, no matter how or where i tap on the pop-up bubble of any event on the iPad, I just can't edit anything as if the edit function does not exist. Yet I have no problem editing events on my Macbook. Am I missing something? Please help. Thanks in advance.
