Any assistance would be appreciated.

Thanks.

I did try that and received the same message.

A critical error has occurred. Object reference not set to an instance of an object.

Thanks for the suggestion...any other ideas would be appreciated.

This is EXTREMELY 110% CONSISTENT on our 5 development, 2 test, and 2 live production environments. Can someone PLEASE shed some light on how to fix this issue?

SINCERELY APPRECIATE every help.

I thank you much.
