Lynn,if you put the 279 in a cell, then in the next two consecutive cells put 280 and 281. Then you can highlight those three and drag it will sequentially fill the numbers.
Lynn,
This is an Access question, not Excel!
gheyman,
You would need VBA code to do that (you cannot really control an Autonumber field - and they shouldn't be used for this purpose anyway).
How is the data entered into the table? If manually through a Form, you can have VBA code run upon new record addition that will populate this field according to your rules.
If you are importing data, you will need to create a process (i.e. Macro) that runs and updates the field after the import.
We can help you with either of those options if you let us know how new records are created.
'Find highest Employee ID in the tblPracticeEmployeeData table and add 1
lngNextID = DMax("[lngID]", "tblPracticeEmployeeData") + 1
'Assign function the value of the Next ID
NewCustID = lngNextID
'Find highest Employee ID in the tblPracticeEmployeeData table and add 1
lngNextID = DMax("[lngID]", "tblPracticeEmployeeData") + 1
[COLOR=#ff0000] 'Make sure number is never less than 279
If lngNextID < 279 Then lngNextID = 279

'Assign function the value of the Next ID
NewCustID = lngNextID
