I replaced your Sex Combobox with a standard Combobox
When you Tab into the Sex Control and type the first Letter of the required Sex it autopopulates.
All very normal. Why go down the route of lots of VB ?
Hi
Normally every table would have an Autonumber Primary Key.
If you need to enter a Unique Patient Number, then this would be a field in your Patient Table.
As for the search Code, which Combobox Control are you trying to search on ?
Hi
Your Relationships window should look something like the attached.
This allows you to create a Main Form based on People with a Subform based on Levels and Ratings.
