I am trying to use a command button on a form to open a report that is connected to a simple select query selecting the current open form per Access 204.  I am using Access 2010.  After writing the DoCmd.openreport code everything works fine until I try to save it. I get an error "The form or report contains changes that are incompatible with the current database format. The form or report was not saved."  I know this code works in Access 2003 so there must be something unique about 2010?  Do I have to do this simple task via Macros perhaps???  The only way to save the form is to change the Has Module option to No which erases all the code I just wrote.  Any help would be much appreciated.
