推荐答案
Somewhere in your code you are using a reference that has not been initialised. This is one of the most common problems reported, but you are the only person that can fix it. The information provided by the system should help you to isolate where it occurs. if not, then you will need to add some debug code to your application.

Hi
The funny thing is everything work 100% if I run it from VS locally.
The problem is Ii get no real error pointing me in any direction when I run it from the IIS server.
Any assistance in pointing me towards a way to get more details as to the error would be appreciated.
I am pulling my hair!!
