All,
I am attaching the following snapshot of the code I
wrote within the HTML and not on the VBIDE.
I am getting the following error on
HttpContext.Current.Session("DeptCode")
System.NullReferenceException: Object reference not
set to an instance of an object.
Why am I getting this error? I don't get this error
when I put this session variable on the VBIDE...it
executes fine. I cheked it by doing response.write.
