[EventCalendar] Javascript Error

[Cathy Cramer]

I get the javascript error posted below when I try to use the prev/ 
next buttons on the calendar. I was getting 3 javascript errors, but  
saw the post about removing extra spaces and was able to eliminate  
two of the error. Is this related to another extra space lurking  
somewhere or is it another problem?

Thanks,
Cathy
