I have named several ranges on my sheet with names of cities such as "newYork", "Chicago", "sanDiego" etc.

I would like to use these ranges in a formula, but rather than type in these ranges I would like to use a cell reference that contains these names.

For example, instead of typing =COUNT(Chicago) where "Chicago" is a range I have defined, I would like to be able to type something like =COUNT(A20) where A20 contains the text Chicago.

I hope I am making myself clear.
Thank you!
