Data tracking and auto sequential numbering

[rajeshparikh64]

I have created an invoice workbook with a small vb code for auto
sequential invoice numbering. I also tried using template wizard with
data tracking to form a database to store the invoices issued. But I
cannot get the auto sequential numbering code get to work with the
template i made for the data tracking.
I will be greatful for the help.
Thanks in advance,
