When attempting to access the Inbox grid I get the message:

"Unable to update Grid Source. Check Source for syntax error, delete fields or non-existing tags. Syntax error in (missing operator) in query expression "((Inbox ) AND (

))'.)

 

If I create a new grid named "test" with the source Inbox field it works fine. 

 

If I change the Inbox grid to a different source, I still get the error.

 

What is the error message above telling me?

Suggestions?

 

Thank you
