Document Template that give serial number to each new saved docuement.

I am trying to create a Template form in Excel for a Request For Quote form.

I would like every time a new document is saved from the template it will give it a new Document number(serial number) in a cell that i specify.

I don't know if the consecutive numbers I want to use should be referenced from DBASE function, a Worksheet, or an XML map.

I am new to Excel 2007 and have not taken any lessons on how to use macros or VBA specifically before..

I understand full well there potential uses and streamlining benefits, but with out any physical training on how to use them I am more or less lost actually trying to apply the concepts.

I really need to make this form successful.

Pleas help from anyone with some ideas!!!!!!!!!!!!!
