Hello Peo, thanks for your input.

I'm absolutely sure that the numbers aren't text. I'd have to admit it's a
bit of a strange (and annoying) problem.If I open the file with an earlier
version of Excel (e.g. 2003) I have no problem.

Are you sure your numbers are not text?

Go to a blank cell, format it as


#,##0

then type in

1000000000

If I do that I get


1,000,000,000


however if the value is text and it comes with the last comma
no numerical formats can change it

Thanks for the response Bob I. However That's what I've done but I get
this
unexpected format. Here's what I mean....

I start with 1000000000
when I select the options as you have said I get 1000000,000 and not
1,000,000,000

That's basically the problem.

If I attempt to format a cell containing the number 1000000000 so that
a
comma separates the thousands I get 1000000,000 instead of
1,000,000,000.

How do I get 1,000,000,000?
