I have created an invoice/proposal template that I want to have the invoice
numbers to be generated automatically to reflect the first three or four
letters of the customers name (in caps), how many times I've done business
with this individual, the month,day, and year of when the invoice was
created, and how many pages in the proposal/invoice were created. An example
of "Mr. Jones" second time doing business with me, written on May 28th, 2005,
and having three parts to the proposal, would look like this: JON0205280503.
Any suggestions would be appreciated.
