Auto-number adding

[Beckwa]

For the booking system I am doing I have set up a workbook containing a booking form worksheet. In this I have a cell for the booking number to go in. I want this number to automatically change every time a new booking form is opened for data entry. A formula was suggested by a friend =SUM(previous number +1) But this wouldn't work - any ideas at all?!?!?!?! cos i'm stuck!! Thanks so much, Bex :D:D

I am a little confused. Do you want the booking number to update everytime you open the workbook or everytime a worksheet is added?

If you wanted updated everytime you open hte workbook then put this code in the code for the workbook:
Private Sub Workbook_Open()
Worksheets("booking form").Range("a1").Value= Worksheets("booking form").Range("a1").Value + 1
End Sub

Where booking form is the name of your booking form worksheet and a1 is the cell where you want the booking number.

I hope this helps,
Kind regards, Al

Every time you select a certain sheet? Right click on the worksheet, select "view code" and paste:

Private Sub worksheet_activate()
Worksheets("booking form").Range("a1").Value= Worksheets("booking form").Range("a1").Value + 1
End Sub
