I want the query to display a 0 if the count is 0. Currently, it displays nothing. How do I fix this?

Here is an example of my SQL:

SELECT Count([ExtendedPrice]) AS [CountOfExtendedPrice] FROM [Order Details Extended] GroupBy [ExtendedPrice] HAVING ((([ExtendedPrice])="100.00"));

So it counts how many times it finds extended price being 100.00

If there are no 100.00's, I want it to say 0 but it currently says nothing at all.

Any help would be greatly appreciated, thanks.
