Error Message when trying to generate a custom report


I customized a Report Style for a Journal Entry Edit List. I used the Standard-SSRS style has my foundation to build this customized Report Style. This report stopped working about 4 weeks ago and now every time I try generating a report I get the following error message:

I understand that in .NET when a method that expects a non-null argument is passed a null value instead, this kind of exception is thrown in but I have not managed to fix my report using this error message.

Any help would be greatly appreciated

Thank you

Is this report based off of a BAQ or tables? If it is based off of a BAQ, please post the pseudo sql for review

Hi Cory,

The report is based off tables.
