I am having a problem with the calendar, that all the sudden stopped working. I haven't done anything to it, but the client might have done something, but they don't know. I am posting the error below, and would appreciate any help with this.

 

Server Error in '/communities/hnr' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Line 52:                 function GetCurrentMonth()
