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?
