VB6 SQL Crystal reports error "This field is not known.

I run a vb6 system that uses SQL and Crystal Reports. The program stops with an error "This field is not known". Could someone tell me how I would find out what field the error is referring to? I have attached a jpg screen shot of the message.
Thanks in advance.

How does the application run reports?
Is it on user selection or does it run a set of reports automatically.

To find the field name you need to know which report it is and the code that is running it.  Generally the issue is the code is changing a formula in the report or the database has changed.

without seeing the relevant code and the report's underlying query, we can only tell you want the error message is telling you: the code/report tries to access some field name which is not there. it might be a typo or a case sensitivity issue ...

WHat code is running when you get the message?

What version of Crystal?

Can you open the report in the Crystal designer?
DO you get an error if you preview it?

We are running Crystal Reports 10. That's what I am trying to find, how do I find the field name that is causing the problem. I believe the vb6 code is running. If I can find the report name I will try opening that in crystal reports designer.
