If you see this error:
"Object reference not set to an instance of an object."
It could mean a variety of things. Double check all the fields in the deal. More than likely, you have a required field that's either blank, incomplete, or incorrect.
It could also be related to your product plans. If you are pulling an older deal into the menu and see this error, it could mean that your product plans have changed since the deal was created originally. In this case, you would need to recreate the deal.
If the information in the deal is complete and accurate, there could be a problem with the VIN. Reference the "VIN Not Recognized Error Message" article by clicking here.
