Hi John,

Does the .DynamicBackColor expression appear valid in the debugger when the error happens? What is the value of lnRow then? Does it correspond to the actual row in the table at the moment?

Very rarely, but I have seen some unexplainable situations with "invalid expression" error message and the grid worked fine before or next time.
