I have two workbooks open (actually, they are two completely separate Excel Files - those are workbooks, right?) I want to close one of them but not both of them.

WorkBooks.Close Book2 gives me an error of "Wrong number of arguments or invalid property assignment"

I looked up Workbooks.Close and find that it does not have, or require, any arguements.....(which would make sense given the error), it just closes everything that is open.

As mentioned, I don't want both files to be closed, just one of them.

So, how would I do that?
