yes, this can be done. IT will require a little knowledge of creating a database table and creating recordsets.
you would need to create a database table to hold the location information:
locationID -Primary Key, Auto Increment
locationName - varchar
locationAddress - varchar
You can then create a recordset to return the locationID and locationName.
Then create a select list in your form to display the locations from the database. Click the select list in design view, and click the dynamic button in the property inspector.
Select your recordset from the Option From Recordset list. Set the Value to use the locationID column, set the name to use the locationName column
you now need to create a second recordset to lookup the selected location. Set it to filter the locationID column on the select list value.
you can use the locationAddress from this recordset in your email.
