I agree with Sam that your requirement isn't 100% clear. He gave a solution for one interpretation.
I'll flesh out mine. =IFERROR(OFFSET(A2,-10,0)+1,1001) =IF(ROW(A2)>11,OFFSET(A2,-10,0)+1,1001) As I said will give you a sequential number that changes every 10 rows, starting with 1001 in A2. If you need to be able to sort your table and have the numbers stay correct, you need a different way to calcualte the book #. This formula calculates the correct book # based on the Receipt #: =(B2-150-MOD(B2-150,10))/10+1001 Change 150 as needed for the starting Receipt #, and 1001 as needed for the starting Book #. You can sort the table with this version, and you can having missing receipts, and the calculation will not be fooled. Maybe one of these meets your needs.

For book #s starting at 1001 and changing every 10 rows; Put in cell A2: =IFERROR(OFFSET(A2,-10,0)+1,1001) In case of Excel version prior to 2003, which doesn't support IFERROR, use: =IF(ROW(A2)>11,OFFSET(A2,-10,0)+1,1001) Change default book # in formula as desired. Copy down.
