The error 'The expression you entered has a field, control, or property name that Access Anaesthetics can't find.' probably means that your group practice has upgraded the satellite file to a more recent version of Access Anaesthetics than the version you are running. Check the versions on the bottom left of the Main Menu. If the data version is later than the program version, go to Maintenance > Web update to obtain the latest program update.

 

If there are no new versions available, try Maintenance Menu > Refresh table links.
