    Hi,

    I am getting the following error when I load the page shown below:

    Code:
    Object variable or With block variable not set. 
    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 variable or With block variable not set.
    
    Source Error: 
    
    
    Line 215:	Response.Write ("<option selected value=""" & MonthCheck(MonthCount) & """>" & MonthCount & "</option>" & vbCrLf)
    Line 216:Else
    Line 217:	Response.Write ("<option value=""" & MonthCheck(MonthCount) & """>" & MonthCount & "</option>" & vbCrLf)
    Line 218:End If
    Line 219:
    I'm stuck, I'm thinking it must be something to do with the Function, MonthCheck, but I'm not making much of it. Any help would be greatly appreciated, thank you.
