How to Put a counter in Excel ?

[maftoun]

I would like to put a counter (number) in my excel sheet. Consider that like a bill number. Any time I open my Excel I want to have new number on top. For example 201, 202 so on and so forth. I would appreciate if anyone had this project before and willing share it with me.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

Please could any one tell me what this code mean

Private Sub TextBox1_Change()

I am working on a little project. I want to put a counter for invoices. I cannot run it. The ultimate goal is when I close and open the Excel the counter should change.

thanks for help
