of course you would need to put it in a sub like this, copy and paste

Sub Invoice_Number()
Sheets("Sheet1").Range("A1").Value = _
Sheets("Sheet1").Range("A1").Value + 1
End Sub

After opening window in VBA editor by entering insert, module,
where do I get the code to insert?

JW69,

To put in this macro, from your workbook right-click the workbook's
icon
and
pick View Code. This icon is at the top-left of the spreadsheet this
will
open
the VBA editor, in Project Explorer click on your workbook name, if
you
don't see it press CTRL + r to open the Project Explorer, then go to
insert,
module, and paste the code in the window that opens on the right hand
side,
press Alt and Q to close this window and go back to your workbook. To
put
the button on your sheet, view, toolbars, forms, click on the button
then
click on your sheet where you want the button, a box will come up to
assign
a macro, pick this macro from the list, OK change the name on the
button if you want to, right click on it to do this. If you are using
excel
2000 or newer you may have to
change the macro security settings to get the macro to run. To change
the
security settings go to tools, macro, security, security level and set
it to
medium


To change the number when you open the workbook

To put in this macro, from your workbook right-click the workbook's
icon
and
pick View Code. This icon is at the top-left of the spreadsheet this
will
open the VBA editor, in Project Explorer double click on thisworkbook,
under
your workbook name, if you don't see it press CTRL + r to open the
Project
Explorer, then, paste the code in the window that opens on the right
hand
side, press Alt and Q to close this window and go back to your
workbook,
now
this will run every time you open the workbook. If you are using
excel
2000
or newer you may have to change the macro security settings to get the
macro
to run. To change the security settings go to tools, macro, security,
security level and set it to medium

I don't know how to insert buttons so Paul B, you kinda lost me.

JW69,

A simple way would be to use something like this, you could assign
it to
a
button, an open or before print event.
Sheets("Sheet1").Range("A1").Value = _
Sheets("Sheet1").Range("A1").Value + 1

BUT, if you did save it as a temple, as you said, that want work,
have a
