Hi @Lewis Corcoran
Perhaps there is an error in this expression in your Tablix. Please click: Tablix Properties-Visibility.
Best regards,

Hi we have a report but get the following error,
The Hidden expression for the tablix ‘StudentDetails’ contains an error: Object reference not set to an instance of an object. (rsProcessingError)
The Hidden expression for the tablix ‘StudentDetails’ contains an error: Object reference not set to an instance of an object. (rsRuntimeErrorInExpression)
There is no visibility expression present on the 'StudentDetails' tablix. Where is this hidden expression located?
